Combined with shanxi YangMei group company be filling mining under villages of xinxing coal mine as the research object, with 811 villages pressed coal geological and mining conditions in the working face as the research foundation, using the probability integral method and mining subsidence visualization system for direct mining caving method for surface movement deformation characteristics of analysis, put forward the feasible method of filling coal mining under villages. And combining with the economic and technology requirements for xinxing coal mine design is reasonable and filling system and packing material proportioning plan, after the application of the probability integral method of filling mining surfaceThrough the practical field investigation, and determine the xinxing coal mine geological occurrence and mining conditions, the village press coal, village situation, such as data, probability integral method and the mining subsidence visualization system is used to determine the direct method of caving mining damage to the surface of the village can not meet the requirements of relevant laws and regulations. According to the requirements of xinxing coal mine filling mining technique, to determine filling mining main ways, process, at the same time of xinxing coal mine filling system design and equipment selection, main technical parameters. Different packing material solidified body using laboratory experiment, on the premise of the economic and technical requirements, determine the reasonable proportion plan of paste filling material, filling in xinxing coal mine working face using probability integral method surface movement deformation is expected, analysis result is expected to impact on the surface of the building, determine the technical and economic rational mining scheme.The research results show that by using the paste filling technology, xinxing coal mine village down coal mining 811 working face of coal seam can be recycled, amount of ground subsidence in conformity with the relevant provisions of the state and the legal requirements, filling mining under villages of xinxing coal mine feasibility studies for YangMei group xinxing coal mine under villages without village relocation filling mining new technology, makes a large number of villages on the will to liberation, increased recoverable coal mine resources effectively, improve the recovery rate of coal resources, extend the service life of mine at the same time, alleviate the resource-exhausted mine workers employment problem, ensure.
Keywords/Search Tags:mining under villages, filling mining, like paste filling, three zones distribution, the surface subsidence is expected
