英文摘要： Deep coal mining dynamic disaster have complex formation mechanism, induced by many factors restrict the development of the dynamic disaster warning technology. In view of the inseparable relation between coal mine dynamic disaster and the coal rock physical and mechanical properties, and the relation between ground temperature and the occurrence of coal seam, and coal mine dynamic disaster is the result of the interaction such as ground stress and gas pressure. The Project using the method of site visits, theoretical analysis, numerical simulation, experimental research and field applications study mechanism of multi-factor coupling warning for dynamical disaster in deep colliery, and accomplish the multi-factor coupled warning for dynamic disaster. Main research contents: (1)The quantitative study of the impact of the physical and mechanical properties of coal and rock dynamic disasters deep coal mining; (2)Establishing the nonlinear mathematical relationship between deep coal mining ground stress and rock pressure; (3)Developing the multi-factor coupled dynamic disaster experimental apparatus, and analyzing the disaster coupled mechanism of ground stress, gas pressure and ground temperature in deep mining conditions,Establishing a nonlinear mathematical model, quantitative studying multi-factor coupling criterion of dynamic disaster; (4) Establishing multi-factor coupled monitoring system, obtain monitor data and analysis the operation effect by field opration, verifying the multi-factor coupling result of experimental and theoretical analysis, and putting forward the deep dynamic disasters multi-factor coupled monitoring and early warning program. Lay the foundation for the development of colliery multi-factor coupling dynamic disaster warning system.
