摘要
合理的煤柱宽度能够保证工作面巷道的稳定性,改善沿空掘巷维护状况,降低由于矿山压力造成的巷道变形,煤柱宽度的确定对于提高煤柱回收率、保障安全高效的生产起到积极作用。本文通过数值模拟研究分析,研究了综采沿空掘巷煤柱的稳定性以及合理的煤柱宽度,为确定合理的煤柱宽度提供了理论依据。
The reasonable width of coal pillars provides the posibility of ensuring the stability of the roadway in the working face,betters the maintenance situation in the driving roadway along goaf,lessen the roadway deformation because of the mine pressure.The confirmation of the width of the coal pillars could be benefic to the recovery rate of coal pillars,plays an active part in ensuring high-productive and high-efficiency.According to the analysis and research of numerical simulation,the numerical simulation suggests the stability of the driving roadway along goaf as well as the reasonable width of the coal pillars.Theoretical basis is provided to determine the reasonable width of coal pillars.
