Study On Visualization Aided Design And Management System Of Gas Extraction

This is an extremely complex and challenging research topic and one of the important content of research in the field of coal mine accident prevention that prevention and control of coal mine gas accident,but prevention and control of gas accident is the most reasonable and effective method of gas drainage.In the actual production,the gas drainage design and standard evaluation and other related work is very complex,artificial calculation error and negligence prone to the phenomenon of coal and gas drainage in coal mine gas accident occurred,leading to the possibility of greatly increased.Therefore,through the study of tunneling face,coal face,goaf and the influence of mining area gas drainage method and gas pipeline parameters calculation method,establish the bottom pumping alley gas drainage hole,high level borehole gas drainage,the gas drainage effect evaluation model,and with the basic theory and programming technology in computer science,using ObjectARX,developed the Visual management system of mine gas drainage.The system is designed tunnel,flow,gas drainage pipeline,gas drainage device,gas drainage monitoring device and other professional primitives,intelligent adaptive intelligent system drawing and editing,graphic control and gas extraction of visual intelligent management based on mathematical function;model procedures,the amount of coal,to participate in the evaluation of residual gas content,residual gas pressure,residual gas content,gas content,analysis of gas drainage rate,gas emission,gas pipeline pumping station capacity,pump pressure,gas pump rated flow,orifice pressure,pipe network resistance,high drilling the parameters of gas drainage hole,standard production capacity,gas drainage,mining parameters such as diameter and blood flow velocity calculation function and gas drainage effect evaluation and report automatic generation Intelligent decision making and prediction functions such as negative pressure prediction and intelligent selection of gas pump.Visual management system of mine gas drainage apply to the Kailuan(Group)Qianjiaying Mining Limited Company,the application results show that the system is stable and intelligent;the evaluation result accords with the requirements of the design and evaluation of gas drainage;gas drainage system can be used for routine design and management work;system can improve the gas drainage design and daily management work efficiency,reduce the error caused by human negligence and calculation,to improve the strength and reliability evaluation,and can reduce the probability of gas accidents.
