煤矿山深浅部开采界线划分问题

The Question about the Boundary Division of Deep of Shallow Part's Coal Mining

结合我国数十处煤矿山开采的实际,提出如何划分我国煤矿山深浅部界线, 通过现场调查和理论分析,探讨了矿山深浅部界线划分的依据及划分的必要性。

How to divide the deep or shallow boundary is put forward in this paper by combining the practice of dozens coal exploitation and what is the dividing proof and what is the dividing necessity are discussed through onthespot investigation and theoretical analysis. The result has some theoretical value for coal mine exploiting.
