应用局部切槽放顶技术处理采空区的研究

摘要

Through the analysis and estimation of stability of goaf of Liaoning Gold Phoenix Gold Mining Industry Co.,Ltd.,adopted the method of caving roof surrounding rock of goaf forcedly in small scope,then released to falling slowly to filling goaf,probably happened pressure bump disaster caused by large scale natural caving of 335# goaf was eliminated successfully,underground safe production was assured,provided experience references for similar condition mine.%通过对辽宁金凤黄金矿业有限公司采空区稳定性进行分析与评价,采用小范围强制崩落空区顶板围岩,而后令其缓慢自行冒落充填采空区的处理方法,成功消除了335#采空区可能发生的较大范围自然冒落造成的冲击地压灾害,确保了井下安全生产,为类似条件矿山提供经验参考。
