摘　　要：为解决柳巷煤矿综放工作面液压支架支护阻力不足难题,以3号煤30112工作面为工程背景,在总结其生产技术条件的基础上,通过理论计算、数值模拟、类比分析等不同方法确定了液压支架支撑高度为2.9~5.5 m,支护强度为1.4 MPa,工作阻力不小于18 000 kN,最终选用ZFY18000/29/55D型两柱掩护式液压支架,达到良好支护效果。In order to solve the problem of insufficient support resistance of the hydraulic support in the fully mechanized caving face of Liuxiang Coal Mine,taking the 30112 working face of the No.3 coal as the engineering background,on the basis of summarizing its production technical conditions,through theoretical calculation,numerical simulation,analogy analysis and other different methods,the hydraulic support height is determined to be 2.9-5.5 m,the support strength is 1.4 MPa,and the working resistance is not less than 18000 kN.Finally,ZFY18000/29/55D type two-column shield hydraulic support is selected to achieve good support effect.
