摘要
底鼓是煤矿巷道中经常发生的动力现象,巷道底鼓使巷道断面缩小,阻碍运输、通风和人员行走,因底鼓而造成巷道报废的现象时有发生,严重影响和威胁安全生产。本文分析了潞新公司二矿W4204综放工作面进风顺槽底鼓的机理,并针对性的提出了加固底角控制回采巷道底鼓的方法,对控制回采巷道底鼓有一定参考价值。
Floor heave is dynamical phenomenon happened regularly in coal mine roadway,floor heave makes section of roadway narrow, which impede transportation ventilation and working.Therefore roadway scraped cause of floor heave happened frequently.This thesis analyzing the mechanism of floor heave in air intake duct in W4204 fully mechanized caving faces in Luxin NO.2 Coal Mine and putting forward method of strength base angle to control recovery roadway floor heave,which have some reference value in control floor heave.
