我国矿区灾难地压控制现状及研究方向

结合中国金属矿山与非煤矿山 3个群次的矿区灾难地压的经历、特点与现状 ,论述了我国矿区灾难地区控制应从 8大主控因素 (地层与岩性、地质与构造、原岩应力、地下水、工程环境、矿山结构设计、开采方法与工艺、支护与安全措施 )、4个层次 (机制与规律、监测与预警、反分析决策、对策与措施 )、中国矿业发展需求、国际科技进步出发拟订正确的研究方向 ,即 :1)重视民采影响、构造应力、水等时空展布规律与作用机制 ;2 )规律的分类分区系统网络化研究 ;3 )建立主动、被动综合监测体系与发展开挖地质灾变预警信息化技术 ;4)完善监测与反分析互补机制、开发管理决策支持系统 ;5 )在确保安全基础上逐步实现信息化开采 ;6)发展交叉学科 ,实现可持续发展 。

Research of prediction for mine earthquake basing on underground rock's movement and deformation mechanism

Movement and deformation of underground rock include vertical dislocation and horizontal deformation,and the energy released by mine earthquake can be calculated basing on deformation energy.So put forwards the prediction for degree and spread of mine earthquake according to the underground rock's movement and deformation.The actual number of times and spread of mine earthquake on site were greatly identical to the prediction.The practice proves the possibility of prediction for mine earthquake basing on the analysis of underground rock's movement and deformation,and sets up new approach of mine earthquake prediction.
