经坊煤矿3701工作面初末采矿压规律观测研究

Observation and Study on the Mining Pressure Law in First and Last Mining Periods of the 3701 Working Face of Jingfang Coal Mine

基于对经坊煤矿3701工作面初末采期间上、中、下3个区域矿压数据的采集,针对性地分析了其顶板围岩运动规律,明确了巷道围岩受超前支承压力峰值影响的位置,为巷道安全回采提供了数据参考和理论支撑。

Based on the collection of the mining pressure data of the upper, middle and lower sections during the first and last mining periods of the 3701 working face at Jingfang Coal Mine, this paper analyzed the law of roof movement of the surrounding rock in details and determined the peak pressure influencing areas of the roadway surrounding rock, which provided data reference and theoretical support for the safe mining of the roadway.
