摘要:
钻井瓦斯抽采工艺现已成为强突出矿井治理煤与瓦斯突出的主要技术手段,然而受钻孔布置、抽采工艺等多因素限制,多存在瓦斯抽采量低、钻孔稳定性差等缺点。基于潘三矿17171(1)低透气强突出瓦斯治理的需要,通过开挖煤岩体的应力分布情况和数值模拟分析,确定了瓦斯高效抽采范围,提出了高效瓦斯抽采带概念;同时,利用3D MAX、Converse 3D对穿层瓦斯抽采工艺进行了三维可视化仿真。试验结果显示:穿层瓦斯抽采工艺在瓦斯抽采效果、工作面防突以及钻井稳定性上均优于其他抽采工艺,单钻井瓦斯抽采速率为134m3/min,抽采总量达1177万m3;同时,平均节省工人培训时间达667%。
Abstract:
The technology of drilling gas extraction has become a main technical mean of coal and gas outburst control in strong outburst mine, but due to the restriction of drilling hole layout, extraction process and other factors, there are multiple shortcomings such as small gas drainage amount and poor drilling stability. Based on the gas control requirements of Pansan Mine 17171 (1) with low gas permeability and strong outburst, by the stress distribution and numerical simulation analysis of open coal mining rock, the range of gas high-efficiency extraction was determined, and the concept of high-efficiency gas extraction zone was proposed. At the same time, by using 3D MAX and Converse 3D, the three-dimensional visual simulation was conducted for the process of gas drainage drilling through layers. Test results showed that: the gas extraction effect, face drilling outburst prevention and stability of well drilling by the process of gas drainage drilling through layers were better than other extraction processes, the gas drainage rate of single drilling borehole was up to 13.4 m3/min, and the total gas drainage amount could reach 1.177 million m3;In addition, the training time of workers was saved up to above 66.7% on average.
