村庄下煤炭资源开采方法研究

Study on Mining Method of Coal Resources under Village

通过分析我国"三下"压煤问题对于煤炭回采的不利影响,提出了解决村庄压煤的一种行之有效方法 --"条采+跳采+全采";对该回采过程形成的条带煤柱应力进行分析,确定了选择适当的采煤方法和地表沉陷与房屋变形监测的安全回采措施。

By analyzing the negative effects of ＂three bellow＂ coal to coal mining, this paper puts forward an effective method to solve the problem- ＂Strip mining＋ Jump mining＋ All mining＂. Through the analysis of strip pillar stress in the mining process, came up with the safe mining measures ,that are select the appropriate mining method and earth＇s surfaee subsidence and deformation monitoring.
