针对永安煤矿特殊围岩地质条件,发明了一种套筒式让压锚杆对北翼采区巷道进行支护参数分析与优化。根据现场实际情况提出支护优化方案,通过数值模拟分析与实地测量对比优化前后效果,得出:优化后的支护方式能有效地控制围岩变形,保证巷道长期有效的服务。 Aimed at the geological conditions of the special surrounding rock in Yong’an Coal Mine, a sleeve-type pressure bolt was used to analyze and optimize the support parameters of the roadway in the north wing mining area. According to the actual situation in the field, the optimization scheme of support is proposed. By comparing the results of numerical simulation with field measurements, the optimized support pattern can effectively control the deformation of surrounding rock and ensure the long-term and effective service of roadway.
