Application Research Of Gas Comprehensive Treatment Technology In 4005 Working-face

Coal is the main energy of China, it's important material to industrial. Mine gas disasters of coal resources exploitation in our country is restricted by the bottleneck, and the corresponding prevention and control of gas disasters and various universities, research institutes and the study of coal enterprise security priority. Over the past 20 years, in the gas disaster prediction, the gas disaster management technology and safety production management has achieved good results, and effectively improve the coal mine safety.Close distance coal seam group mining working face gas emission of affected by many factors, such as upper and lower adjacent layer and the coal seam gas content, gas pressure, mining method and craft, ventilation mode and air volume of workin face, the surrounding rock properties, etc. Under this conditions, the gas comprehensive control are different in difference working face. The 4005 working face of a coal mine in Hunchun as an example in this paper, analyzed the gas comprehensive control to working face by theoretical analysis, field test and data statistical analysis and other methods, and made an estimate to the application effect of the measure. By test, determine parameters of gas comprehensive control technology in working face.Basised on the research of gas control technology in working face at home and abroad, analyzes the main reason for 4005 face roadway, and obtained ideal effect of governance:the work of top corner gas concentration and return air lane gas concentration from 4.6%-4.6%, respectively,4.6% to below 1%, transfinite number from a dozen times a day three times down to 2 months, greatly improved the working efficiency of 4005.
