摘要
突水事故是目前我国煤矿生产过程中面临的严重灾害之一,对矿井的安全生产有很大的影响。由于对陷落柱突水问题的不够重视,我国曾发生多次突水事故,损失惨重。综合分析陷落柱突水事故得出该类突水具有突发性、突水量大、经济损失大且治理困难等特点,给矿井的安全生产工作带来了巨大的危害。因此,加强对陷落柱突水机理的研究工作,特别是在矿山压力作用下的突水机理,并进一步研究相应的的防治办法,具有十分重要的意义。本研究针对首阳煤业8103工作面地质条件复杂,即受陷落柱、断层影响和顶板稳定性差等特点,对该工作面放顶煤开采中工作面过陷落柱以及构造、采场围岩控制技术等进行系统研究,最大限度地提高煤炭资源回收率,同时实现工作面的安全回采。
Water inrush from coal mine has become one of the major disasters in the face of coal production,which seriously affect the safety of mine production. Because of insufficient attention to the water out burst of collapse column, water inrush accident had repeatedly occurred in our country and lost heavily. Comprehensive analysis of previous water inrush accident from collapse column obtain that water inrush from collapse column has some notable features, such as occurs suddenly,large amount of water, large economic losses and difficult to control etc.Which has brought great harm to safe production, environmental protection, people＇s livelihood and social stability.Strengthen research work of the mechanism of water inrush from collapse column, especially the mechanism of water inrush from collapse column under mining pressure,and to study the prevention measures of water inrush have very important significance.In this study, for the complicated geological conditions of 8103 face in a mine, namely by the effect of collapse column and fault, poor roof stability etc. Conducted a systematic study to how to passing the collapse column and construct safely, as well as surrounding rock control technology, to maximize the recovery of coal resources and achieve mining work safely.
