Shed

"Environmental protection is a barrier that coal enterprises have to take. The country's environmental protection threshold for the coal industry will be higher and higher in the future. As production and trade, we need to pay attention to environmental protection while grasping production benefits. In the field of environmental protection, the company must carry out rectification according to the requirements of the government. Everyone in the company must raise the awareness of environmental protection, start from individuals, start from production and start from business. Only by taking the initiative, can the company not be "driven away” and develop continuously. " Chairman of company, Gan Guohua, said.

Under the leadership and guidance of the board of directors, the coal washery of Longkai, Xingyi and Ronghua Industry and Trade started to construct shed projects at the same time last October, with a total investment of nearly 16 million yuan. From civil construction to grid installation, and to the installation of color tile roof panels, it has been pushing forward intensively. Only those who are in the process know the hardships and efforts.

” Coal Washery and coal yard’s shed construction is a major environmental protection project of the company this year. During the construction period, production should be taken into account. Safety is the first. Everyone should go all out to give unconditional support. "Gan Changshou, the head of the coal washery, gave instructions at the meetings many times. The biggest difficulty of shed construction is that it cannot does not affect the daily production of coal yard, the production and construction is cross-cutting, mutual influence and mutual restraint.

Because the construction of coal yard shed occupies one third of the original coal yard, such as foundation excavation, material stacking, large-scale machinery and equipment, so that the storage of raw coal is greatly reduced. It is necessary to rationally plan the stacking and intake pace of coal yard. Originally, raw coal can be stored for one month, but now it can only be stored for about 10-15 days. When only 3-5 days are left for a certain kind of coal, it is necessary to urgently transfer goods and contact the coal mining company to import raw coal. If there are delays in transportation or coal mines, the consequences are really unthinkable. Fortunately, the Nanning-Kunming Railway new freight yard built in last July and August can temporarily store tens of thousands of raw coal, which can be used as an emergency response. Meet an emergency. Indeed, the raw coal comes early and has no space to store, and comes late and delays production. Therefore, the coal washery must cooperate well with the construction and reasonably allocate the coal intake pace so as to ensure that both production and construction are correct and that the clean coal is delivered to customers on time and the quality is still awesome.

Cross-construction and production also bring challenges to safety. Unloading of coal trucks, stacking and cleaning of loaders in coal yards, and feeding of coal from loaders to inlet and outlet of coal loaders will all conflict with construction projects. Mutual communication and coordination must be made to make way of the site so as not to affect production and construction as far as possible. In order to prevent collision with construction equipment, a warning line is demarcated before each start-up, and the loader will honk and warn before start-up. On the one hand, it is necessary to support the smooth construction of big shed, on the other hand, to ensure the accuracy and stability of coal blending. Both sides must take into account, which is quite a test for field staff.

The construction of the shed adopts a large-span reticulated shell structure. The installation process uses the support of the tire frame and the high-altitude cumulative slip construction technology, with good lighting, advanced technology, fast progress, and guaranteed project quality. In order to ensure the construction progress as planned, the company set up the coal yard shed project department responsible for material procurement, construction safety, construction progress, quality supervision, environmental management, etc.. The department will also intervene in construction projects, from the source of material procurement to construction project construction, carry out strict supervision, standardize various acts of contractors, and timely arrange and solve the problems on site with contractors.

Quality is the key to project construction. In order to ensure the quality, the coal washery shed project department always puts the construction quality at heart. For each step, every acceptance is strict, rigorous and does not leave any room for it.

As a shed project manager, Luo Ruigang often goes back and forth to Ronghua Coal Washing Plant and Longkai，Xingyi Coal Washery, especially to the key civil construction links. Every day, he goes to the site to inspect. If there is a problem, he immediately requests rectification. Since entering the project department, Meng Yanfeng of the project department has tied himself up with the shed project, and has never had a day off except during the New Year. He is a veteran of the army, hard-working, eager to learn,he spare no effort to buy steel, color steel and other materials in Guangdong, and with Luo Ruigang patrols steel binding, template installation, bolt tightening in place, he also often climb more than 20 meters high on the tire frame to check the installation, the construction quality of frame columns and the groove elevation and plane size of the foundation, the specification and size of steel bars to do acceptances of spacing, section size and height of formwork, inspection report of members of grid, surface quality of solder joints and tightness of bolts, and immediate rectification is required whenever problems arise.

It is understood that the shed project can save costs after putting into use, the closed freight yard will not be affected by wind and rain, this can reduce the loss rate of coal and open-pit coal yard, stabilize production, avoid the impact of excessive moist caused by continuous rain for a long time to push coal into the coal mouth, can also reduce the total amount of dust and sewage, and achieve win-win environmental and economic benefits.
