摘要
以王楼煤矿11301综采工作面为研究对象,首先分析了煤层的地质条件与顶底板的情况,并制定了矿压观测的内容与方法,进而对综采支架工作阻力、单体液压计的工作阻力、巷道围岩变形进行实测分析,得到矿压显现的规律,从而为工作面的高产、高效、安全、低耗创造良好的技术条件。
This paper based on Wanglou coal mine 11301 full mechanized working face. It analyzed the geological environment,the roof and floor of the coal bed firstly,then made a plan for strata control observation, did an actual measure and analysis of the fully mecha- nized support working resistance, the single hydraulic prop yield load and the roadway wall rock distortion,resulted the law of the ground behaviour. So it can make a nice technique condition for high -output,high efficiency,safety and low expend.
