道路穿越煤田采空区预留煤柱的技术措施研究

为了开发和利用废弃矿区老采空区土地,提高矿区土地利用率,缓解矿区土地资源紧缺的矛盾,开展采空沉陷区土地资源的开发和利用工作已经迫在眉睫。该文通过乌鲁木齐外环路东北段穿越六道湾煤田采空区的工程实例,介绍了道路穿越煤田采空区预留煤柱路段确保路基抗变形措施的方法、注浆处理的技术和检测路基抗变形效果的检测方案等。其技术措施可供同行借鉴。

Study on Technical Measures of Road Crossing Reserved Coal Column Section of Goaf in Coal Field

In order to develop and utilize the old goaf land of waste coal field,to enhance the land utilization rate of coal field and to relieve the contradiction of the land resource shortage in coal field,it has been extremely urgent to carry out the development and utilization of the land resource in the goaf.Taking the engineering case of the northeast section of Outer Ring Road crossing the goaf in Liudaowan Coal Field in Urumchi as an example,the article introduces the measures to ensure the deformation resistance of roadbed when the road crosses the reserved coal column section of the goaf in coal field,the technology of grouting treatment and the inspecting test scheme to inspect and test the deforming resistant effect of roadbed.The technical measures can be referred for the similar projects.
