鲍店煤矿5303-1工作面安全煤岩柱留设研究

On safety rock pillar setting and reservation at 5303-1 Face of Bao Dian Coal Mine

本文通过《规程》预计,类比分析和经验公式计算等手段,对鲍店煤矿5303-1工作面上覆岩层破坏高度和防砂安全煤岩柱尺寸进行了计算,得出了在5303-1工作面在顶分层开采条件下和综放开采条件下保证工作面安全生产的合理参数,并且对工作面提高开采上限提出了一系列的安全措施,对同类型矿井的设计起到一定的参考意义。

Through Regulation forecast, this paper, by analogy analysis and empirical formula methods, carries out calculation of overburden damage height and sand control rock pillar dimension with 5303-1 face of Bao Dian Coal mine, and comes to reasonable parameters that could ensure safety production with top slicing mining and fully-mechanized top coal caving mining conditions at 5303-1 face of Bao Dian Coal Mine. It also puts forward series of safety measures for enhancing mining npper limits, acting as a reference to mining plan of similar coal mines.
