在小窑破坏区下有效提高掘进效率的方案分析

Scheme analysis on improvement of tunneling efficiency under small kiln destruction area

在井工开采过程中,时常遇到小窑越层越界开采,小煤窑内经常有积水积气现象。大型矿井在进行采掘活动时,本着"安全第一,预防为主"的安全生产方针,需要及时排除小煤窑对于采掘不利因素的影响,所以能否快速探明并且及时排除小煤窑内不利因素的影响就成为影响掘进效率和采掘衔接的重要因素,通过在汾孝矿区的实践,及时合理地施工探巷可以有效提高掘进效率,保证采掘衔接。

During the process of well drilling,there is often a small kiln crossing the boundary and mining.There are often accumulated water and gas in small coal mines.In the mining activities of large mines,in line with the safety production policy of＂safety first,precaution crucial＂,it is necessary to eliminate the influence of unfavorable factors of mining in small coal kiln in time.So it is an important factor to quickly detect and eliminate the influence of unfavorable factors in the small coal kiln in time.Through the practice in the Xiaoxiao mining area,timely and reasonable construction of the laneway can effectively improve the tunneling efficiency and ensure the mining connection.
