一、前言 正当芦别矿业所进行井下巷道总体布置时,各盘区的布置是从深部水平掘进上山开始的。在设立独立的通风管路之后,掘进了石门和煤层巷道,从而形成岩石巷道串联的通风系统。今后将通过采用下山掘进法来达到以下指标: 1.在断层、折皱等的影响下,上山工作面遇到断层和接近煤层时,作为防止瓦斯措施的强化区会受到限制,但在下山掘进中可利用上部巷道的独立分流回路,因此不妨碍盘区的展开。
I. INTRODUCTION Just as Luxi Mining Company conducted the overall arrangement of underground tunnels, the layout of each panel started from the deep horizontal tunneling. After the establishment of independent ventilation ducts, tunnels and coal seams were excavated to form a ventilation system in series with rock tunnels. In the future, the following indicators will be reached by adopting the tunneling method: 1. Under the influence of faults, creases and the like, the reinforced area as a gas prevention measure is restricted when a mountainous working face encounters a fault and approaches a coal seam. However, Can use the upper shunt independent shunt loop, so does not hinder the expansion panel.
