摘 要:阐述了陷落柱的特点,结合下霍煤矿1306综采工作面的实际情况,在回采过程中遇到的陷落柱地质状况,以及历次通过陷落柱的情况,针对不同类型的陷落柱采取相应的通过方法,并结合这些方法以及取得的经验,对1306综采工作面回采时过陷落柱进行方法选取,同时优化回采过陷落柱的安全措施,对综采工作面的过陷落柱有一定的指导意义。This paper expounds the characteristics of collapse columns. Combined with the actual situation of 1306 fully mechanized mining face of Xiahuo Coal Mine the geological conditions of collapse columns encountered in the mining process, and the previous conditions of passing through collapse columns, this paper adopts corresponding passing methods for different types of collapse columns and these methods and experience. This paper selects the method of passing through the collapse column in 1306 fully mechanized mining face,and optimizes the safety measures of passing through the collapse column, which has certain guiding significance for passing through the collapse column in fully mechanized mining face.
