摘要
危岩崩塌是贵州省煤矿开采引发的主要地质灾害类型之一,为了正确地分析该类危岩崩塌的稳定性、科学合理地制定防护措施,以保证在保障人民生命财产安全的基础上减轻地质灾害治理成本,以某煤矿内老鹰岩危岩体为例,在分析其稳定性的基础上,采用RocFall数值模拟分析滚石的影响程度及范围,提出了“整体稳定、局部崩落”的总体结论并制定了“被动网+落石槽+监测”的被动防护措施,治理效果良好,可为类似项目提供参考。
Dangerous rock collapse is one of the main types of geological disasters caused by coal mining in guizhou,in order to correctly analyze the stability of dangerous rock collapse,set up a scientific and reasonable protective measures,and to ensure that on the basis of people’s life and property security governance costs and reduce geological disasters in a coal mine in the eagle YanWei rock mass as an example,on the basis of analyzing its stability,Rocfall numerical simulation was used to analyze the impact degree and range of rock,and the general conclusion of “overall stability,local caving” was put forward,and the passive protection measures of “passive net+rockfall trough+monitoring” were formulated.The treatment effect is good,which can provide reference for similar projects.
