阜新地区矿山地质灾害及其防治对策

Mining geological hazard and its control countermeasure in Fuxin region

阜新地区是具有百年开采历史的煤炭工业区 ,矿山地质灾害对矿区正常生产和人民安全生活的影响十分严重 ,在我国煤炭工业城市中具有典型的代表意义。本文对矿区内的地面沉陷、露天矿滑坡、煤矸石堆放、瓦斯灾害等各类矿山地质灾害的分布范围、灾害规模和造成后果等进行了论述 ,确定矿区发生地面沉降的面积已近 10 0 km2 ,煤矸石堆放已占地 32 .1km2 ,是最为严重的地质灾害 ;露天矿滑坡则主要分布在海州和新邱露天矿 ;瓦斯灾害主要出现在井工矿中。这些矿山地质灾害对矿区生产和市区生存环境影响严重。通过对这些灾害的地质背景、形成机理、发育条件的分析 ,根据不同的工程地质条件对各种矿山地质灾害提出了防治对策。

Fuxin region is a Coal\|mined industry area which is a hundred years old where mining geological hazard seriously affects normal production and people's safety. Study on this region has typical representative significance among coal industry city of our country. This paper discussed the distribution,calamity scale and sequence of all kinds of mining geological hazard such as ground subsidence,landslide of opencast mine slope,coal gangue piling,coal mine gas hazard,confirmed that the area of ground subsidence is about 100 km 2 and area coal gangue piling is 32\^1 km 2,both of them are the most common mining geological hazard.Sopes distribute around Haizhou and Xinqiu opencast to coal mine landslide occurs and gas happens in every mine. These problems are very serious for production and circumstance. According to the analysis of geological background,formation mechanism, development conditions and engineering geological condition,countermeasures applied for all kinds of mining geological hazard are formulated in the paper.
