冲击地压矿井可研阶段区域防冲设计方法

Design method for regional burst prevention in feasibility study stage of rockburst mines

针对目前矿井设计阶段对于区域性预防冲击地压系统性设计方法和体系尚未建立的问题,为了在新建矿井设计阶段将区域防冲理念融入到矿井主要方案中,降低矿井生产期防治冲击地压工作难度和强度,分别从矿井可研阶段冲击倾向性的确定途径和方法、冲击地压矿井设计生产能力确定、冲击地压矿井开拓部署实现区域防冲理念、开采顺序与区域防冲结合等方面,提出了将区域性防治冲击地压理念融入矿井前期设计的步骤和方法,并结合呼吉尔特矿区北部矿井进行了设计实例应用,为其他类似新建冲击地压矿井可研阶段区域防冲设计提供借鉴。

At present,the systematic design method and system for regional prevention of rockburst have not been established in the mine design stage.In order to facilitate the design department to integrate regional awareness of rockburst prevention into the main plan of the new mine design stage,and reduce the difficulty and intensity of preventing rockburst during the production period of the mine.The steps and methods are proposed for integrating regional awareness of rock burst prevention and control into the preliminary design of the mine,including determining rock burst tendency in the feasibility study stage of the mine,determining production capacity of rock burst mines,implementing regional burst prevention concept in the development and deployment of rock burst mines,and combining mining sequence with regional burst prevention.The proposed methods were applied in the northern mine in the Hujirt mining area,which can provide reference for the regional burst prevention design during the feasibility study stage of other similar newly built rock burst mines.
