摘要
Abstract
By using the methods of theoretical analysis and numerical simulation, compared the roadway supporting effect when the design coal pillar width are different, analyzed the abutment pressure distribution law in coal pillar and gob side after mined in Sanjiaohe coal mine 2-506 large mining height working face, so as to determine the optimum coal pillar size. At the same time, using the technology of high pre-stress bolt supporting can maintain the roadway integrity, the support structure reflected the good and active bearing capacity. The control effect is remarkable, which greatly improves the recovery rate of coal, and improves the production efifciency of coal mine.关键词
