矿井巷道掘进率控制技术及应用

Control Technology of Roadway Drivage Ratio in Mine Shaft and Its Application

在矿井开采设计过程中,不断优化巷道布置方式,建立完善通风、提升运输、供电、供排水等生产系统的同时,降低巷道掘进率是一项重要任务。阐述了矿井巷道掘进率对生产管理、生产成本的影响和某些工程实践对掘进率的影响,介绍了几种回采巷道掘进率增高的工程案例,对确定合理的掘进率有重要意义。

In the process of mining design in mine shaft,it is an important task to reduce drivage ratio as well as optimizing the layout of roadway,establishing production system such as ventilation system,hoisting transportation system,power supply system,and water supply and drainage system.Introduced the influences of roadway drivage ratio to production management and production cost,the influences of some engineering practice to drivage ratio were also mentioned.Some project examples of increasing drivage ratio of gateway were elaborated,which has important significance for determining reasonable drivage ratio.
