摘　　要：为避免XV3308综采面在利用联络横川施工撤架通道作业过程中受坚硬顶板周期来压影响,提前采用水压致裂工艺对采面顶板进行弱化处理的同时补强联络横川支护强度,采取工作面整体调斜局部调直后快速推进,有效减弱了顶板来压威胁,确保了撤架通道的工程质量和安全施工。In order to prevent the XV3308 fully mechanized mining face from being affected by the periodic pressure of the hard roof during the construction of scaffold removal channel with crossheading,the hydraulic fracturing technology is adopted in advance to weaken the roof of the mining face while strengthening the supporting strength of the crossheading,and the rapid advance after the overall tilt adjustment and local straightening of the working face is adopted,which effectively reduces the threat of roof pressure and ensures the engineering quality and safe construction of the withdrawal channel.
