摘要
煤矿采空区地质情况复杂,地下空洞多变,单体体量相对较大,地基处理困难,工程建设安全风险较大。通过运用自主研发的“先封堵巷道后充填采空区,浆液先稀后浓,4个阶段分批施工,一次成孔全段注浆”地基处理技术,可实现煤矿采空区坍塌土地的综合利用,并为今后同类型工程的建设提供安全、可靠的技术支持。
The coal mine goaf is characterized by complex geological conditions,varied underground cavities,relatively large single volume,difficulty of foundation treatment and great safety risks in engineering construction.In this paper,through the use of the foundation treatment technology developed independently,which can be described as“sealing the roadway firstly,filling it then;thinning the the serous fluid firstly,thickening it then;carrying out the four stages of construction in batches;the holes formation at one time and grouting in the whole stage”,the comprehensive utilization of the collapsed land in coal mine goaf is realized.And this technology can provide safe and reliable support for the construction of the same type of project in the future.
