摘要
在铁路地质选线工作中,采空区选线一直以来是一个重要研究内容。在西北某煤矿专用线铁路采空区地质选线工作中,我们运用资料收集、地质调绘、物探、钻探等综合勘察方法,查明了选线工作中控制性工点D1K33+160隧道的采空区分布范围、特征等,并对穿越采空区的控制性因素安全煤柱宽度和安全顶板厚度进行了分析确定,指导了采空区线路选线和优化工作。
It has been an important research content for the location of mined-out area in the railway geological line selection. In the geological line selection of a special railway line for coal mine in goaf of northwest region,some comprehensive survey methods such as data collection,geological surveying and compiling,geophysical prospecting and drilling were applied to identify the goaf distribution range,characteristics of D1K33 ＋ 160 tunnel in the controlled engineering. In addition,the key factors of safe coal pillar width and thickness of the roof in mined-out area were analyzed and determined. It could guide the line selection and optimization in goaf.
