大采高综采工作面液压支架选型研究及应用

Selection and Application of Hydraulic Support for Fully Mechanized Mining Face with Large Mining Height

基于山西煤炭运销集团马家岩煤矿工作面的地质条件,根据支架选型原则,通过系统分析比较法进行工作面的液压支架选型,采用经验公式及矿压理论进行液压支架主要参数计算,通过计算出的参数以及支架的结构要求确定支架型号,为井下大采高综采作业提供理论及实践依据。

Based on the geological conditions of the working face of Majiayan coal mine in Shanxi Coal Transportation and Marketing Group,type selection of the hydraulic support for the working face is carried out by the system analysis and comparison method according to the principle of support selection. The main parameters calculation of the hydraulic support is carried out by adopting the empirical formula and the ore pressure theory; and then the support model is determined according to the calculated parameters and the structural requirements of support. It would provide the theoretical and practical basis for fully mechanized mining with large mining height.
