五凤矿中一采区6中煤层煤与瓦斯突出区域预测

Coal and Gas Outburst Regional Prediction of the Middle of the Sixth Coal Seam in First Mining Area of Wufeng Coal Mine

煤层瓦斯赋存规律研究和突出区域预测划分的准确性是确保突出矿井安全生产的关键,同时也是瓦斯治理的基础。以五凤矿为例,通过大量资料的收集、整理及现场瓦斯参数的测定,综合考虑煤体结构参数及煤层瓦斯含量、瓦斯压力等参数,采用单项指标法和综合指标法进行煤与瓦斯突出区域性预测,进而划分出该采区在测定标高(+1 540 m)以上为非突出区域,+1 540 m以下是煤与瓦斯突出危险区域。

Studying on distribution rules of coal seam gas and accurately dividing outburst regions are the key work to guarantee mine safe production. In this paper,taking Wufeng Coal Mine as an example,through a large number of data collection,arrangement and the determination of local gas parameters, consideration of the structural parameters of coal body, coal seam gas content and gas pressure, the single index method and comprehensive index method were carried out for regional prediction of the coal and gas outburst ,then mining area was divided into two regions,the elevation（ ＋ 1 540 m） above is the region without coal and gas outburst danger, ＋ 1 540 m below is the region with coal and gas outburst danger.
