The Study Of Structure And Its Impact To The Coal Mine Safety Production In The North Of Hancheng

Coal mine at the north of Hancheng is rich in coal resources, but the complex tectonic background is diffult for exploration in the region.The study to the structure and its controlaction on gas will not only help reduce or avoid disasters, but also exploit the resouses.This paper mainly studies the tectonic characteristics in the northern of Hancheng and the coal mine safety factors in the process of production such as gas, water bursting and roof caving influence of disasters. First of all, based on the analysis of the study area, the basic structure of tectonic distribution rule and tectonic style type were summarized, think north several field for overall structure form towards north north east, tendency towards north cc, along with the tendency of a single wave shape ups and downs, large and medium-sized tectonic not inclined structure development, mainly is fold, small fault and layer slide structure primarily. Then on the structural evolution and dynamics mechanism, this paper tries to form the phase iii ancient tectonic stress field. Then, with the aid of pre-production mine and exploration income drape fault tectonic stress distribution to the material and the grasp of the numerical simulation, author, and further analyzed the research area not proven and untapped area roughly structure circumstance. Finally, based on the disaster situation especially research in the gas, water bursting tectonic cause of accidents and roof caving, the author thinks that the analysis of the safety of coal production structure has great harm, especially gas outburst is the region's primary problem. Know and prediction of the structural trend not mining production safety future some guidance.
