Study On The Warning Technology Of Unoutburst Coal Seam Of Jincheng Mining

The purpose in this article mainly is to study on promotion forewarn idex and marginal value of the unoutburst seam of 3#seam in Jincheng mining. In order to establish the parameter system and warning method of promotion of the unoutburst seam for 3# seam in Jincheng coal field,from gas geological theory the paper adoptse the methods of statistics data,control analysis of geological structure,measurement and analysis of gas geology data,laboratory study and so on.Studied the coalfield structure,stress,gas and the distribution of soft coal from coalfiled structure,and sunned the principal character of coal and outburst and the major factor that controlled coal and outburst of 3# seam in Jincheng mining. Studied the distribution of coalfield structure and the evolution of coal structure and so on of jincheng coal field, and so on, the character of structure and the character of soft coal,law of gas occurrence controlled by coalfiled structure in jincheng coalfiled was summed .By analysised the omen of outburst,the measured basic parameter and outburst data,and juxtaposed gas geology index which determines and so on, has established the promotion forewarn parameter system which included eperience idex,gas content, structure coal thickness,and gas emission of 3 # seam,marginal value of the promotion forewarn determined by analysis daily forecast idex, measured warning idex and laboratory research.
