摘要
根据淮北矿务局桃园煤矿1015工作面现场观测资料,详细分析了大倾角单体支柱工作面初次来压和周期来压的矿压显现规律,验证了工作面沿倾斜方向单体支柱载荷呈“马鞍形”分布特征,讨论了大倾角工作面顶底板移近量与支柱初撑力之间的内在关系,并且根据1015工作面的具体条件,提出了保证大倾角单体支柱工作面安全开采的有效措施。
Abstract Based on the field measurement data from No.1015 working face, Taoyuan Mine, Huaibei Mining Bureau, the ground pressure of individual prop supported face in steep thick coal seam is analyzed during first weighting and periodic weighting. It is verified that the distribution of load acted on the props in working face is in a saddle type along the dip direction. The relationship between the roof-to-floor convergence and initial support resistance of props is also discussed. Furthermore, the measures for the safely mining of No.1015 working face is proposed.
