First, the company profile
Beijing Xingfa Cement Co., Ltd. is a Sino-foreign joint venture. It is located in Huaibei Town, Huairou County, Beijing. It is 62km away from Beijing in the south, Huaifeng Highway in the west, and the Great Wall in the north. There are many tourist areas nearby, surrounded by mountains and green mountains. ,nice environment. The company now has a cement clinker production line with a daily output of 720 tons. Since the joint venture in October 1994, with the continuous investment of the company and the joint efforts of all employees, the company has undergone rapid changes in environmental protection, safety, production, quality and cost. The operating rate and daily output of the kiln continued to increase year after year. The annual clinker production increased from 70,000 tons in 1994 to 319,000 tons in 1999, which was 4.6 times that before the joint venture and exceeded the design capacity by 59%. At the same time, important technical indicators and economic indicators such as production cost, power consumption, and heat consumption have been greatly reduced. The quality of the products has been significantly improved and has been well received by users. Established its own brand image in the Beijing market.
The company has a large limestone mine with a total proven reserves of 130 million tons and a reserve of 110 million tons. The ore quality is good, low alkali and high calcium, suitable for the production of low alkali cement. Open pit mining, road transportation development, 10 meters a step, using medium-deep hole differential blasting, after ore mining, three times broken to the cement plant.
Second, comprehensive utilization of mineral resources to improve environmental protection
As the company is located in the Huairou Tourism Resort in Beijing, the company's environmental protection work is the top priority of the company's development. After the joint venture, the company invested a lot of manpower and resources to strengthen environmental governance and environmental protection. In particular, it has made great progress in improving employees' environmental awareness. The company's goal is to "provide a safe and comfortable working environment for our employees." Through several years of efforts, the company's main emission indicators are all lower than national standards. In 1998, it passed the environmental protection acceptance of Beijing and became a model for environmental protection of cement enterprises.
Resources are not renewable. In order to use resources reasonably and efficiently, the company has done a lot of work in the mines. Firstly, the original geological data was reorganized and studied, and the mining site was supplemented and encrypted to make the geological conditions more clear and reliable. On this basis, the Lafarge Technical Service Center produced a nugget model for guiding mining. The ore is reclassified according to the CaO grade: permacalcd, calcareous and low calcium stone, and the three ores are used in combination according to the target value during production. The company's long-term goal is zero waste. At present, only clay wet mud is not available due to the conditions of the crushing equipment. But this resource will be recycled in the company's long-term planning.
By greatly reducing the stripping ratio, the source of pollution is reduced, the waste disposal site is less occupied, the damage to vegetation and soil erosion are reduced, and the mining cost is reduced and the economic benefit is improved. This is the most outstanding achievement in our mine environmental protection work.
The noise pollution and dust pollution of the crushing workshop is an important part of the mine production affecting the environment. The most prominent parts of noise and dust generation include dumping ore, ore crushing, screening and belt transportation to the original mine silo. The second is the noise generated by the mining truck and the road dust. The noise source of the crushing and screening equipment is strong, about 100 decibels, and the maximum dust concentration reaches 242.3mg/m 3 . For this reason, the crushing and belt transportation are closed buildings, the operation control room is sealed better, and the ore transfer bin door is also Hang the curtain to minimize the spread of noise and dust. The operator strengthens personal protection, equipped with earplugs and dust masks, strengthens the outdoor greening, and plantes tall trees as a barrier. In the feeding port, belt conveyor transfer station, crushing equipment and vibrating screen, anti-suction type flat belt dust collector and other types of bag type dust collector are provided, the dust removal efficiency is 99%, and the total exhaust air is 500000m 3 /h. The dust concentration of the dusty air is 600 to 1500 mg/m 3 , and the dust concentration of the air after the treatment is less than 50 mg/m 3 .
In order to reduce the dust on the road surface of the mining car, and also to maintain the road to protect the car, it is equipped with a special water truck road sprinkler. The original mine mouth is also sprayed with mist spray when it is unloading, and the dust removal effect is very good.
Greening and beautifying, creating an excellent environment The company attaches great importance to environmental protection. Under the big capital, the equipment is transformed and the environment is beautified. The company has a greening team, professional greening staff, environmental protection departments and professional environmental protection personnel. Greening and beautification has a unified plan, and each department has its own territory, each with its own characteristics. Beautifying the environment has become the pursuit of every department. At present, trees are planted on both sides of the road and in the free area, and flowers are planted and grass is laid. In order to restore the damage to the landscape, since 1997, the company has stopped the waste from the edge of the mine and invested human and material resources to restore the covered vegetation. At present, significant results have been achieved. Today, the company's chimney does not smoke, the road does not fly dust, and the birds and flowers are in harmony with the surrounding environment.
Environmental monitoring. The main tasks of environmental monitoring are: regularly monitoring the environmental quality of the mining area, monitoring the pollutants (such as dust, noise, harmful gases, etc.) generated during the production process, monitoring the discharge outlets and pollutants discharged, and formulating the company for the enterprise and the competent department. Provide environmentally sound planning, strengthen environmental management, and provide a reliable basis for improving pollution prevention and protection of the ecological environment. [next]
Implementing land reclamation and restoring the environment In 1995, the company's mine technology department completed the design of mine land reclamation and restoration of the environment, and carried out phased reclamation and greening of the mine. The service life of the mine is between 80 and 100 years. The lowest elevation of mining is +75M. It is used as a reservoir in the gob area of ​​+75～+89M, and it is more than 90M to reclaim land or plant fruit trees. The mine reclamation rate was 23.8% and the greening rate was 2.63%. At present, the company plans to gradually withdraw mine recovery costs. The chart below shows the company and mine landscape before the joint venture, in 1998 and after the mine was mined.
Third, put people at the core of the enterprise
Summarizing the company's development process over the past few years, we believe that in addition to Lafarge's mature cement production technology and management experience, the most important thing is that we always put people at the core of the company and gradually formed a company within the company. A team of employees who love and develop for the company; and gradually establish an effective management system that can motivate employees to make progress.
1 Employee training The quality of employees includes both the quality of the business and the loyalty to the cause. Since the company's starting point is relatively low, improving the quality of employees is a prerequisite for the company's development. In order to improve the management quality and technical quality of managers and ordinary employees, the joint venture company has invested a large amount of manpower and resources to train employees according to the different needs of different periods and different personnel. This includes hiring famous foreign companies and experts to teach the company, asking foreign experts to come to the factory to guide the work, asking famous domestic experts and colleges to teach the company, internal training and sending employees to receive training within the Lafarge Group at home and abroad. In the past few years, the company has invested millions of dollars in employee training and received the expected results.
At the same time, we also pay special attention to training in daily practical work. This type of training is low cost, but it can often receive more obvious results. The purpose of the training is not only to improve the professional quality of employees, but also to establish a united and progressive team within the company to establish a good corporate culture.
2. Improving the working environment environment of employees is critical to the company's development. It not only gives a good impression to outside visitors, but more importantly it directly relates to employees' work mood and physical and mental health. In the past few years, we have done a lot of work in many aspects, from environmental governance, accident analysis and prevention to improving the quality of canteen services, in line with the principle of caring for employees and starting from the immediate interests of employees. The quality of the factory and the work, living environment and safety of the employees have been improved.
3. Correctly evaluate the contribution of employees to the company.
The company stipulates that each employee should have at least one face-to-face assessment each year, so that each employee has the opportunity to exchange face-to-face views with his immediate supervisor. These include: reviewing the performance of the previous period, affirming the achievements made, pointing out the shortcomings, and making employees aware of their efforts. At the same time, employees can have the opportunity to present their personal development wishes to their superiors. This greatly enhances the communication between the upper and lower levels, effectively motivating the work of employees. At the same time, it also helps managers to make continuous improvements based on the opinions of their subordinates.
The company always puts its employees at the core of the company. It is based on this that employees will have the feeling of being proud of working in the company, in order to stimulate the enthusiasm of employees. The company can get rapid development.
The above is for reference only by leaders and experts. Please advise if you are not correct.
