摘　　要：为了研究煤矿上下行钻孔瓦斯抽采技术的适应性以及瓦斯抽采效果,在保德煤矿81309工作面开展了上下行钻孔瓦斯抽采技术现场试验。试验结果表明,在同等瓦斯治理效果条件下,上行钻孔抽采的平均瓦斯浓度、瓦斯抽采纯量、百米钻孔抽采量要比下行钻孔高;在相同抽采条件区域范围内,上行钻孔抽采瓦斯浓度比下行钻孔高1.134倍,上行钻孔抽采平均纯瓦斯流量比下行钻孔高1.296倍;在同等抽采、地质条件煤层区域范围内,上行钻孔比下行钻孔具有更好的抽采稳定性和抽采效果。试验研究结果将对煤矿瓦斯治理方案中优选上下行钻孔瓦斯抽采技术提供一定参考。In order to study the adaptability and effect of upward and downward boreholes gas drainage technology in coal mines,the field test of upward and downward gas drainage technology was carried out in 81309 working face of Baode Coal Mine.The test results show that under the condition of the same gas control effect,the average gas concentration,the pure amount of gas extraction and the extraction amount of 100 meters boreholes are higher than those of downwards boreholes.In the area with the same drainage conditions,the average gas concentration of upward boreholes is 1.134 times higher than that of downward boreholes,and the average pure gas flow rate of upward boreholes is 1.296 times higher than that of downward boreholes.In the coal seam area with the same extraction and geological conditions,the upward boreholes have better extraction stability and effect than the downward boreholes.The experimental results will provide a certain reference for the optimization of upward and downward boreholes gas drainage technology in coal mines gas control scheme.
