石灰岩顶板长壁工作面矿压规律计算预测与实测对比

Comparison between Prediction and Detection of Mining Pressure among Longwall Working Face with Limestone Roof

根据晋城泊村煤矿15号煤层15201长壁工作面的具体地质条件,采用采场薄板矿压理论对工作面矿压进行了计算预测,并与现场实际矿压观测结果进行了对比分析,其理论计算预测与工程实测结果基本一致。文章对类似地质条件和开采技术条件下的工作面矿压规律计算预测具有重要的理论意义和工程价值。

According to the geological condition of 15201 longwall working face of No.15 coal seam ot Bocun Mine, Jincheng, calculation and evaluation of mine pressure on working face are carried out based on the thin-board pressure theory. The result was compared with the real observation. The prediction is basically correspondent with the observation. The study bears theoretical meaning and engineering value for the mining under the similar geological and technological conditions.
