【摘要】 以鲁西煤矿微震监测工程为例,介绍了在井下应用微地震(M S)技术监测覆岩导水裂隙带高度的方法。通过与其它方法的对比,认为用微地震(M S)监测技术确定导水裂隙带高度是可靠的。该技术的推广应用对确定开采上限和保障煤矿安全生产等有重要意义。更多还原

【Abstract】 Taking for example the microseism(MS) Monitor engineering of Luxi Coal Mine,the methods to monitor the height of water flowing fractured zone of cover rock in underground by the MS technology are presented.Based on comparison with other methods,it considers that it is reliable to determine the height of water flowing fractured zone by the MS monitor technology.Popularization and application of this technology are of great importance to determination of upper limit of mining and assurance of safety production of coal mines.更多还原
