富水软岩地质条件下综采工作面的回撤一直是困扰榆树井煤矿生产的重大难题,受工作面顶板破碎、淋水及回撤通道底鼓等影响,工作面回撤后期出现困难,经过不断摸索,在11505工作面回撤时,采取了一系列的创新工艺,26 d回撤支架,创造了临沂矿业集团大型综采工作面回撤最快纪录.
富水軟巖地質條件下綜採工作麵的迴撤一直是睏擾榆樹井煤礦生產的重大難題,受工作麵頂闆破碎、淋水及迴撤通道底鼓等影響,工作麵迴撤後期齣現睏難,經過不斷摸索,在11505工作麵迴撤時,採取瞭一繫列的創新工藝,26 d迴撤支架,創造瞭臨沂礦業集糰大型綜採工作麵迴撤最快紀錄.

Under the geological condition of soft rock and water-rich, the withdraw technology of fully mechanized mining face had been a difficult problem for Yushujing coal mine. Because of the broken roof, water spraying, and floor heave of the withdraw roadway, it is difficult to withdraw the supports in the later period. With hard work and effort, this paper proposed a series of innovative technologies in the withdraw process of NO. 11505 working face in Yushujing coal mine. The whole process used 26 days, which is the fastest record among all withdraw technology of fully mechanized mining face in Linyi mining group company.
