摘要
水体下安全采煤问题是煤矿企业面临的技术难题之一。针对郑煤集团芦沟煤矿32采区的煤层覆存、地质构造、水文地质、采煤方法等具体地质采矿条件及地表五星水库的现状,在计算防水安全煤岩柱尺寸的基础上,结合地表移动和变形预计,对五星水库下开采的安全性进行了分析。经过计算分析认为:五星水库下进行煤层全采是安全可行的。目前,首采的32101工作面采后是安全的,从而验证了此计算分析是科学、可靠的。
The issue of the safety mining under the water body is one of the technical problems faced to the coal mine enterprises.According to the seam deposit,geological structure,hydrology,mining method and the certain geological and mining conditions as well as the surface Five Star Reservoir status,base on the calculation of the size for the water prevention safety coal and rock pillars,in combination of the predictions of the surface ground movement and deformation,an analysis on the safety of the coal mining under the Five Star reservoir was conducted.After the calculation and analysis,it held that a full seam mining under the Five Star Reservoir would be safety and feasible.At present,the first coal mining face-No.32101 coal mining face was safety after the face mining completed,which could be verified that the calculation and analysis was scientific and reliable.
