大倾角俯伪斜放顶煤放煤工艺研究

以薛村矿92712综采放顶煤工作面作为研究对象,运用模拟实验对轻型支架放顶煤的放煤规律进行研究,并通过工作面现场试验,测定出合理的放煤参数,解决了在大倾角俯伪斜条件下合理使用轻型放顶煤回采工艺的难题,保证了矿井安全、稳产、高产,进一步提高了矿井的经济效益,为开采类似条件下的煤层积累了经验。

Large Dip Argle Pseudo-pitch Top Coal Caving Technology Study

Taking Xuecun Mine Xuecun mine 92,712 coal caving face as the research object,using simulation experiments on the light support caving to study coal caving law,through the experiment on site,a reasonable caving parameters to solve the same conditions was determined,which solved caving mining technology challenges using lightweight,ensuring mine safety,stable and high yield,providing experience under similar conditions for the coal exploitation coal.
