小型煤矿环境地质问题及防治对策——以湖南涟源地区为例

Geological Environment Evalution for Small Coal Mines——Taking Lianyuan for Example

湖南涟源地区煤矿多属小型矿山,但小煤矿的开采同样会引起诸多环境地质问题,如瓦斯灾害、煤矿水灾、地裂缝与矿坑疏干排水引起的地面岩溶塌陷、煤矸石堆放破坏土石环境等,这些问题需要评估和解决。笔者针对上述问题进行了成因分析、规律探讨,并对每项环境问题提出了保护与治理方案。

Mining coal may induce many geoenvironmental problems, such as mine gas explosion, gas and rock outbursting, mine water bursting, mining pollution, mining ground subsidence and so on. These problems should be evaluated and solved. Their causes of formation and distributing factors are discussed, then the solutions for the problem are provided briefly. They are usefull for coal mine geoenvironmental evaluation.
