摘要
在研究林华煤矿煤层赋存、水文地质及煤层瓦斯参数的基础上,通过系统的分析论证,确定林华煤矿一采区首采层优选9~#煤层。首采9~#煤层可有效提高煤矿瓦斯治理水平,改善工作面作业环境,缩短达产时间和投资回报期。在当前煤炭行业不景气的大环境下,更有利于林华煤矿的发展。
On the basis of that studying of coal seam occurrence, hydrogeology and coal seam gas parameters in the Linhua coal mine, through systematic analysis and argumentation, determining of the preferred 9# coal seam as the first mining layer in the one mining area of the Linhua coal mine, the level of gas treatment in coal mine can be effectively improved by first mining 9# coal seam, improving working environment of working face, shorting the production time and the payback period of investment. Under the current bad environment of the coal industry, it's beneficial to the development of Linhua coal mine.
