Rock Stability Evaluation And Treatment Program In Coal Mine Area

Because of the exploitation of coal recourses, the bases of energy in middle and western have occurred lots of goaf, and the bearing capacity of foundation on the goaf have been dropped significantly. With the development of western, the speed of urbanization is accelerated, and the shortage of ground for construction, the factory and residential construction is built on the goaf area. The treatment and prevention technical and formation mechanics have significant theoretical value. Based on the coal mine of goaf in town of Shenmu, the deforming and formation mechanics, failure of foundation, distributing of goaf and dynamical treatment scheme are studied generally in is paper. The specific content as follows:Firstly, the fundamental mode of goaf settlement and distributing is introduced briefly, which is preparing for the research work of deforming and failure mechanics of Sha Goumao coal mine.Secondly, through the analyzing of upper rock of goaf movement, the regular of ground deforming amount on different site up on the goaf.Thirdly, through the analyzing of areal geological environment, formation, deforming, failure mechanics and stability of Sha Goumao coal mine, the character and regular of goaf settlement are generalized. Moreover, the evaluation of goaf stability is fixed through the failure and ground settlement mechanics.Finnaly, based on the situation of Sha Goumao coal mine, the omnibearing and detail optimization of treatment and prevention program is presented with the fuzzing analytic hierarchy process. At last, the program of ground injection is fixed.
