古山煤矿大倾角工作面液压支架的选型及应用

摘要

通过对古山煤矿地质条件的分析，利用数值模拟法和估算法确定了支架的主要技术参数和结构特点；并针对古山矿工作面大倾角的特点，选择了相应的布置方式，有效改善了支架受力状态，使长期难以解决的端头复杂支护问题得到简化。%Though analyzing the geological conditions of Gushan Coal Mine, the main technical parameters and structural features of the support are determined by the numerical simulation and estimation. Aimed at the characteristic of large dip angle work range in Gushan Coal Mine, the corresponding arrangement form is chosen. It effectively improves the strained condition of support and simplifies the chronic problems of complex support at the termination.
