摘要
为提高煤巷掘进条带瓦斯治理效果,通过在新疆艾维尔沟矿区2130煤矿4号煤层24223运输巷开展基于定向长钻孔治理煤巷条带瓦斯的水力压裂试验,考察瓦斯治理效果。试验结果表明:相比于传统瓦斯治理手段,定向长钻孔高压水力压裂技术平均抽采瓦斯浓度和平均抽采瓦斯纯流量分别提升了2.4倍和4.0倍,抽采达标经济成本和时间成本分别降低了80%和67%,可以有效提高煤巷条带瓦斯治理效果,降低瓦斯治理成本。
In order to improve the gas control effect of the coal roadway driving strip,in 24223 transport lane of No.4 coal seam in 2130 Coal Mine in Aiweigou Mining Area of Xinjiang,by carrying out the hydraulic fracturing test based on directional long borehole to control gas in coal roadway strip,the effect of gas control was investigated.The test results show that compared with the traditional gas control method,the average gas extraction concentration and the average gas extraction purity of the directional long hole high pressure hydraulic fracturing technology are increased by 2.4 times and 4.0 times respectively,and the economic cost and time cost of the extraction standard are reduced by 80%and 67%respectively.It can effectively improve the gas control effect and reduce the cost of gas control.
