摘要
在煤矿井巷中,回采巷道的长度约占整个矿井巷道长度的70%左右,随着综采技术的不断发展,回采巷道长度不断扩大,特别是机轨合一巷的应用,使得巷道断面逐渐增大,回采巷道矿压显现非常剧烈,巷道破坏愈加严重。因此,找到矿压显现规律,进行有效的支护,将对维护巷道稳定和保证矿井的正常生产起到重要作用。通过对两巷的矿压观测及理论分析,得出了中厚煤层的矿压显现规律,并做了支护技术上的相关研究。
The length of the mining roadway about accounted for the whole mine laneway length of about 70% in a coal mine roadway. With the developing of the technology of fully mechanized mining, mining roadway length expands unceasingly, especially the application of machine and track comprehensive transportation roadway, making the roadway section increase gradually, the underground pressure behavior of mining roadway is powerful, roadway destruction has become more serious. So find the mine pressure appeared regularity and effectively support, it has played an important role to maintain the roadway stability and ensure normal production in the mine. Through the underground pressure observation and theory analysis to two roadways, it is concluded that the underground pressure appeared regularity in the medium - thick coal seam, and carry out the related research of the supporting technology.
