摘要
沿空掘巷窄煤柱宽度的合理确定不仅可以提高煤炭资源的采出率,而且可以降低巷道维护难度、改善巷道维护状况。通过理论计算、数值模拟及工程实践对于窄煤柱的技术要求,最终确定郭屯煤矿1303工作面轨道顺槽沿空掘巷窄煤柱的宽度。
Reasonable determination of narrow coal pillar width in gob--side entry driving can not only improve the recovery ratio of coal resources, but also reduce roadway maintenance difficulty and improve roadway main- tenance status. The narrow coal pillar width in gob--side eiatry driving on 1303 face of Guotun Colliery is finally determined by theoretical calculation, numerical simulation and the technical requirement of engineering practice for narrow coal pillar.
