煤与瓦斯突出构造物理场研究

This project takes the tectonophysical field of coal and gas outburst as the core content. Based on analyzing the relationship of coal and gas outburst and mine geological factors, this project selects typical coal and gas outburst mines as the main study area in Pingdingshan, Zhengzhou,Jiaozuo mine area, and comprehensively applies theories and methods of gas geology, tectonophysics and rock dynamics. By applying instrument and experimental methods and adopting field research and laboratory stimulating experimental study, the relationship of tectonophysical field and coal and gas outburst is discussed. It mainly includes the control effect of tectonic deformation field, tectonic stress field and gas field on coal and gas outburst; coal and gas outburst mechanism under tectonophysical multi-field coupling effect; establishing coal and gas outburst tectonophysics field theory and testing it by applying the research results to large-scale coal and gas outburst accidents analysis and the prediction of coal and gas outburst, finally, consummating the theory of tectonophysical field.
