金川不良岩层中巷道的变形破坏十分严重,是影响金川有色金属公司生产成本和矿山建设的关键所在。多年来,围绕不良岩层中巷道地压的控制管理,金川有色金属公司组织了几十个科研、设计、生产、高校等单位的科技人员进行联合攻关,并取得了不少重大成果。但是,要想真正把握金川不良岩层中地压显现的规律,制定一套有效控制高应力破碎岩体中巷道地压的措施,还有待进一步的深入研究。本文所介绍的“金川1号岩石力学试验巷道的设计与施工”:是采用喷锚网支护结构,利用二次支护方法,制服金川高应力破碎岩体中巷道围岩变形破坏的一个示范。
Jinchuan poor rock formation deformation and destruction of roadway is very serious, is affecting Jinchuan Nonferrous Metals Company production costs and the key to the construction of the mine. Over the years, Jinchuan Nonferrous Metals Corporation has organized dozens of scientific and technical personnel in scientific research, design, production, universities and other units to conduct joint research and control and achieved many significant results around the control and management of roadway pressure in poor rock formations. However, it is yet to be further studied in order to truly grasp the law of ground pressure in Jinchuan bad rock formation and to develop a set of measures to effectively control the roadway pressure in high-stress broken rock mass. This article describes the “Jinchuan No. 1 rock mechanics test tunnel design and construction”: is the use of spray anchor net support structure, the use of secondary support method, the uniform Jinchuan high stress broken rock tunnel surrounding rock deformation and destruction of a demonstration .
