近距离薄煤层群开采技术方案综合评价
|
摘要
为合理有效的开采出煤炭资源,采用UDEC数值模拟软件对枣庄泉上煤矿三采区近距离16,17煤层开采方案进行了比较,从岩石的抗拉破坏强度,裂隙发育程度和导水裂缝带高度及底板破坏深度方面综合评价了泉上煤矿在采用单一煤层开采和联合开采16,17煤层时的采动破坏情况,为矿井选择合理的开采方案提供了理论依据。
For reasonable effective mining of the coal resources,applying the numerical simulation software UDEC to compare Zaozhuang Quanshang three mining 16,17 close seam mining schemes.From rock tensile strength of destruction,crack growth degree,water flowing fractured zone and depth of destroyed floor comprehensive evaluation on coal seam 16,17 mining damage of Quanshang mine using a single coal mining and the combined mining is carried out,theory basis for the rational choice for mine mining scheme is providesd.
