摘要
平顶山煤矿区是我国大型煤矿区,近年来大规模的开采,致使地下水水位大幅度下降,地表呈现不同程度的沉陷和河流污染,诱发了瓦斯爆炸、水土流失,地表开裂等多种地质灾害。现从煤矿开采的正负两面出发对这些问题及其产生的机理进行了详细的讨论并针对各种环境问题提出了保护与治理措施。
Pingdingshan coal mining area is a large-scale coal mine area in China. Due to extensive mining recently, the groundwater level is declined, the earth surface is subsided in variable degrees and the river is polluted, which induce multi-geological disasters, such as gas explosion, water loss and soil erosion and earth surface＇s cracking, etc.. From the viewpoint of effective and negative in coal mining, the problems and their mechanisms caused by coal mining are discussed in detail, in which protec- tions and solutions are given according to different environmental problems.
