摘要:
以潘一东矿1252（1）下保护层首采工作面为研究对象，采用分源预测法对下保护层工作面瓦斯涌出情况进行预测。计算结果表明，1252（1）工作面的瓦斯有六成左右来自上邻近13-1煤层，在本煤层回采期间提出了地面钻井、底抽巷穿层钻孔、高位钻场顶板走向钻孔、沿空留巷充填墙埋管等瓦斯治理方案，抽采率达到90%左右，工作面上隅角完全杜绝瓦斯浓度超限现象，保护范围内的13-1煤层的突出危险性也显著降低。
Abstract:
In this paper, the 1252 (1) first mining face of lower protective layer in Pan Yidong Mine was taken as the object for study, and the differentsource prediction method was applied on the lower protective seam to predict gas emission situation. The calculation results showed that about 60% gas in the 1252 (1) face came from the upper adjacent 131 coal seam. Some gas control plans such as coal mining in the ground, end pumping lane borehole, high drilling yard roof drilling, filling gob wall pipe were put forward in the process of stopping. The extraction rate could reach 90%, and the gas concentration gauge in upper corner was completely elimated, the risk of outburst in the protection range of 131 coal seam was also significantly reduced.
