摘要
通过对开滦矿务局赵各庄矿11、12水平的实测,探讨了受采动影响的深井底板岩巷围岩松动圈的变化规律,并在该矿11、12水平进行了工业性试验。试验获得了预期的成功,维护费用降低了45.7%。
Based on a field observation in the 11th and 12th mining levels of Zhaogezhuang coal mine,this paper investigates the influence of extraction on the thickness of a broken zone around a deep roadway locafed in seam floor. On the above basis, an industrial test has been successfully carried out in both the mining levels, which made the maintenance cost of two experiment roadways decreased by 45.7%.
