梧桐庄矿密集村庄下采煤技术研究

Research on the Mining Technique under the Intensive Villages of Wutongzhuang Coal Mine

在总结国内外相关技术的基础上,提出了梧桐庄矿密集村庄下采煤全局性的技术思路和协调式跳采技术思想。根据南神岗村煤柱的开采设计分析了协调式跳采对村庄房屋的影响,通过村庄下开采试验和地表移动观测结果分析,得出这种开采技术对于村庄下煤炭的高效开采有着重大的意义,对其他类似条件下的"三下"采煤工作也具有重要的指导作用。

Based on summing up some related techniques at home and abroad,this paper puts forward the overall technical idea and cooperative jump mining technical concept on the coal mining under the intensive villages of Wutongzhuang Coal Mine,and according to the design of Nanshengang Village＇s pillar mining,analyses the impact of the cooperative jump mining on village houses,and through the mining test under the village and the analysis on observed results of surface movement,comes to that this coal mining technique has great significance on the high-efficiency coal mining under villages and has important guiding function for the coal mining under buildings,railways and water bodies with similar conditions.
