The dissertation is devoted to a solution of the traumatism prevention problem from a complex of natural extraordinary manifestations of mine pressure when developing coals of various degree of a metamorphism below a zone of gas weathering. For the first time from discharging positions when unloading the mechanism of destruction of the coal-rock massif, caused by memory of breeds and consisting in development after deformations of genetic return deformations elastic restoration , change of steam volume structure, allocation of the gas-saturated solutions, allowing to explain and the reasons of emissions of coal and gas is opened. It is experimentally established that advancing reduction by preparatory developments of lavas leads to reduction of emissions intensity in 3-4 times and promotes decrease in a traumatism from collapses in cavities of the emissions occurring at detonation. Criterion validation of category especially mine-bed discharge is executed and proved that to start its decontamination, in case of overworking, it is necessary to create an advancing, allowing to provide a maximum gas recovery. Lack of coals endogenous fires in ZGV, when developing high reworked anthracites, tendency locality to self-ignition proves development need of new, more reliable, economic and technological express ways of their forecast and prevention, including and at coal and gas emissions. They should consider the results of studying of a community of the nature of formation of self-ignition received in work and a outburst hazard. Key-words: traumatism, beat rock failure, coal and gas rush, massif overworking and underworking.
