摘要
针对七一新发煤业五采区开采过程中面临的相邻矿井老空水灾害威胁的问题,对五采区水害原因进行分析,并结合现场实际地质生产条件,采用理论计算和数值模拟方法研究确定邻近矿井老空水的防水煤柱宽度为55m。现场实践表明,留设55m防水煤柱可以有效预防老空水突水,确保煤矿安全生产。
Aimed at the problem No. 5 mining area of Qiyi Xinfa Coal lyzed, and the water-proof coal pillar theoretical calculation and numerical conditions. The practice showed that prevent the goaf water inrush so that of goal water disaster from adjacent mines during mining in Mining Company, the reasons for water disaster were anain width of 55 m was determined for the adjacent mines by simulation combined with the actual geological production the water-proof coal pillar in width of 55 m could effectively the safe production of coal mine was ensured.
