Research And Development Of The Standard Evaluation System For Gas Drainage And Its Application On Tangshan Mine

Along with the increase of mining depth,the number of outburst mines and coal seams also continue to increase.Gas disasters are becoming more and more serious.Gas drainage is one of the widely used and effective methods among the technology to solve the problem of mine gas.An important reason of abnormal gas emission,coal and gas outburst,gas burning and gas explosion happened in mine is the gas drainage didn't work well that should be extracted but didn't extracted or the effect of the gas drainage did not meet specified requirements.Therefore,it is of great significance to appraise of gas drainage in mine reaching standard.Coal mine enterprise safety production information means backward,mine safety monitoring,monitoring system is not perfect is an important reason for the occurrence of coal mine accidents.In the face of the current status of the coal industry,the overall level of information is not high,for the gas drainage standards evaluation,On the basis of theoretical analysis of the influence factors of gas drainage and gas drainage,the evaluation system is established.System function mainly includes the basic condition evaluation,the pipeline resistance calculation,the gas pump capacity verification and selection,etc.At last,the application of the standard evaluation system of gas drainage is applied to the assessment of gas drainage in Tangshan,and to evaluate the gas drainage in Tangshan mine.
