The Preliminary Design On Green Mining Of Chaxin Coal Mine In Nayong County

Chaxin coal mine in harmony county, the area is small, the number of minable seam mining field, coal quality is good, simple geological structure, coal seam gas content is higher. Development layout in this paper, Chaxin coal mine puts forward different schemes comparison, according to the situation of Chaxin coal mining, and closely around the basic characteristics of the mine, the reasonable development deployment, on the first underground mining, transportation design, to ensure the rational exploitation of resources. At the same time, this paper develops the current situation of the development of mining in coal mine at home and abroad, actively adopt advanced and mature technology and equipment at home and abroad and the advanced production technology, adjust measures to local conditions to improve the degree of mechanization, the construction of high production and efficiency of modern mine.In terms of the main equipment selection, according to the actual needs of the mine air volume, production capacity, length, Angle of roadway, calculated to select the advanced and mature technology and equipment at home and abroad, enhance the mechanization level of mine.The sulfur is one of the harmful elements in coal, which brings great harm to coal exploitation and environment, the paper through the analysis of coal quality, occurrence of sulfur in coal, choose a kind of low energy consumption, less pollution, green microbial desulfurization method, greatly reduces the coal emissions of SO2. To mine disaster factors and damage degree analysis, and puts forward prevention measures to realize the green mining.Finally based on the construction of Chaxin coal mine planning, investment estimate for the project, and analyses the economic benefits of the project.
