Electrical and Mechanical Technology Research of Fully Mechanized Coal Caving under Aquifer

Abstract:

In this paper, We studied the technical issues of fully mechanized caving under aquifer in Tiebei mine of Zhalainuoer mining company，carry on analysis and studies from the electrical and mechanical equipment to the technical management and gave the solution, with some reference value. It is hard to mine one by one coal seam due to hydrogeology and deposit of2a seam, Tiebei mine. For example, It is hard to solve top seam management, hydrogeology management and coal Spontaneous combustion. For getting more coal and extend the service life of mine, We started trial coal mechanized caving under aquifer in 2004 on the research basis. At the beginning of coal mechanized caving, We encountered equipment problems, equipment assort usage problems，produce management problem, coal caving method problem, use of face-end support problem, water management problem, and so on. By continuously review experience and exploring ,We solved the problems one by one. So we gained coal mechanized caving under aquifer valued experience.
