天安集团十一矿综放面支架适应性分析
Adaptability analysis of the support for the sub level caving face of the 11th mine in Tian’an Group Corporation
【摘要】 综放支架的合理性与否直接影响着工作面的高产高效 ,本文根据现场实测对平煤集团十一矿己1 6 - 1 7-2 2 0 80综放面支架的适应性进行了分析 ,得到支架的初撑力偏低 ,在来压前的工作阻力为 2 3 88~ 3 5 0 1k N,来压时的增载系数为 1 .1 2~ 1 .1 5 ,所选用的支架是合理的。
【Abstract】 Whether the supports for the sub level caving mining are rational or not relates directly to the high yield and high efficient of the working face, based on the local survey, this paper analyzes the supports adaptability of the working face in Pingmei Group Corporation and some conclusions are made that the support setting loads relatively low, the working resistance value is 2388-3501 kN before the press comes, the increasing load modulus is 1.12-1.15 as the press comes and the support selected is rational.
