炮采放顶煤工作面矿压显现规律研究

Research on Law of the Presentation of the Mine Pressure with caving-working-face

以何庄煤矿11013工作面矿山压力实测数据为依据,分析了炮采放顶煤工作面矿压显现规律,并对支柱初撑力、工作面支护密度、工作面支护方式、放顶煤工艺和超前支护提出了合理化建议。

At basis of the mine pressure measured data in He-Zhuang Coal Mine 11,013 working face, analysising of the law of the pre-sentation of the mine pressure with caving-working-face, and putting forward of reasonable proposals about setting load, the density of support, support Way, caving mining craft, leading support.
