| 摘 要： | 150801面是新集矿区推覆体夹片下开采的第一个工作面,由于南东翼采区推覆体夹片局部富水,推覆体夹片水将威胁150801面的安全回采;通过对推覆体夹片水文地质条件的进行分析,并对150801面安全开采的可行性进行了论证,提出了150801面推覆体夹片下留设48 m防水煤柱开采可行性;通过开采实践证明:150801面推覆体夹片下防水煤柱48 m的开采是可行的,为矿区相似条件下全面提高回采上限提供了技术依据。

| Abstract: | The nappe lane in the east-south coaling face has too much water locally which will threaten the safe coaling of 150801 face that is the first one under the board of the nappe lane in Xinji Mine.This paper puts forwards that it is feasible to build 48m water-proof coal column in the nappe lane of 150801 face,according to the scientific analysis of hydrology and geology.Moreover,it is an effective way by practice,so it provides the technical support to some mines that has similar situation. |
