摘要
从煤层预抽瓦斯方法、钻孔布置等方面介绍了冯营矿研究区段煤层瓦斯抽采情况。通过现场实测煤层残存瓦斯含量、残存瓦斯压力,并结合相关实验参数计算煤层瓦斯抽采率,对研究区段煤层预抽瓦斯效果进行整体评价,认为该区段煤层预抽瓦斯效果达标,但仍存在一些问题。对存在问题进行分析,并提出了一些建议。
Introduced gas drainage situation of researched section coal seam in Fengying Coal Mine from coal seam gas predrainage methods, the borebole layout, etc. The overall evaluation was made through the methods of measuring residual coal seam gas content, residual coal seam gas pressure, and calculating coal seam gas drainage rate by the relevant experiment parameters. It was thought that the gas predrainage effect of researched coal seam is standard,but there are still some problems,some comments were also put forward according to analysing current problems.
