Structure Development Law and Evolution to Gas Control in Qinglong Mine

In order to prevent the gas accidents occurred in Qinglong Mine, based on the systematic regulation and analysis on the geological information and gas i nformation of Qinglong Mine, in combination with the analysis on the regional structure evolution, the paper had a discussion on the structure development law and evol ution features of Qinglong Mine, an introduction on the structure control effect of the mine gas deposits and a prediction on the gas outburst danger areas. The results s howed that the structure formation of the Qinglong Mine was in Yanshan period, the structural complexity was medium-complicated, the reversed fault was developed, t he gas content was high and the gas content of each seam almost was over 10 m3/t.In combination with the analysis on the seam depth and structure coal distribution | aw, it held that the structure complicated area in the south-west part of the minefield was a gas outburst danger area and the east part of the minefield was a gas outbur st threatened area.
