The Study About Surface Movement Regularity Of Mine By Drilling Solution In XinLi Chemical Company

Compared with the lane mining, rock salt water-soluble method has many uniquefeatures in the mine surface mobility characteristics. This will lead to theories and methods oflane mining can not be applied directly. Combined with the characteristics of rock saltwater-soluble method, to Hunan XinLi chemical industry company as an object, this paperresearches the regularity of surface movement by water dissolution of rock salt mining areas.The paper' mainly works have the following:(1)Accoring to the characteristics of high-yield agricultural region and waterconservancy facilities and the building characteristics in Liyang plain, thesis combines withthe corresponding regulations and the requirements of observation, establishes the surfacemovement observation network, and monitoring the surface movement of mine, and thedeformation of buildings and agricultural lands. To realize early warning and alarm, preparethe ground for ensuring security in mining areas.(2)Develop a software of mining surface movement monitoring data processing andanalysis-Project Monitoring Information System. Its sistem can effectively realizemanagement, publishing and analysis about Hunan Xinli chemical industry company's minesurface movement monitoring data, ensure the safety of mine management work and lay thefoundation for research on surface movement regularity.(3) Comparative analysis of XinLi chemical company in the east part of western,monitoring data: mining area surface subsidence and subsidence of the Western average ratesignificantly greater than in the east part of. Through field survey and analysis of mining area,mining area of Western influenced by faults, cavity roof under water erosion, destruction, notconsistent with the prediction of surface movement regularity of the stochastic medium theoryis expected. Therefore, the paper using probability integral method to new Li chemicalcompany mining surface movement prediction, selection in the eastern part of surfacemovement observation data analysis.(4)Study that the original geological survey report, on the mining surface subsidenceparameter, does not take into account the cavity shape, insoluble residue and dissection of theexpansion and filling, as well as the stope pressure water backwater effect on the miningsurface consistent beneficial effect, resulting in a predicted value and measured value of bigdeviation. The use of subsidence observation data of surface subsidence parameters areobtained, and the drilling solution mining surface movement prediction model is correctBased on the monitoring of surface movement by drilling solution in Liyang, this paper studies the corresponding surface movement and deformation regularity and gets the surfacemovement prediction model and control method of surface movement and deformation ofmine mining by drilling solution mining in Hunan Xinli chemical industry company.
