According to the roadway driving problem of Juji Coal Mine with large buried depth,high current force,soft rock,gas outburst,in order to increase the amount of coal recovered from gob side entry driving with non-pillar,it is proposed that there be gob side entry driving with non-pillar of No.2604 working face.During the excavation,firstly,the roadway is arranged in the pressure relief area to reduce the pressure of the roadway,and the permanent support is supported by the anchor wire mesh+squeezable 29U steel column;secondly,water drainage is used instead of drilling and drainage to control the water;the third is through construction.The high-level drilling holes in the roof are used for gas prevention and control.Fourth,the roadway is arranged in the pressure relief area to reduce the amount of gas control work and improve the anti-outburst effect.The results show that adopting measures such as roadway support,exploration and drainage,gas prevention and control,and anti-outburst management measures,compared to the same conditions,the working area of other working face under the same conditions is more than 30 to 40 m per month,effectively achieving with non-pillar are driven along the road.%针对车集煤矿大埋深、高地应力、软岩、突出矿井掘巷困难的现状,为了实现无煤柱沿空掘巷以增加回采煤量,提出在2604工作面下平巷完全无煤柱掘进期间,一是巷道布置在卸压区以减少巷道压力显现,采用锚网索+可缩性29U型钢柱进行永久支护;二是采用追排水代替钻探放水进行防治水管理;三是通过施工顶板裂隙高位钻孔抽排瓦斯进行瓦斯防治;四是巷道布置在卸压区减少瓦斯治理工程量并提高防突效果.结果表明:通过研究并采取以上巷道支护、探放水、瓦斯防治、防突管理等措施,有效地实现了无煤柱沿空掘巷.
