Safety Evaluation and Optimization of Coal Mine Ventilation
In order to solve the problems of insufficient air volume and unreasonable distribution of wind resistance caused by the extension of ventilation lines and the reduction of local cross-sectional area as the working face advances,a comprehensive evaluation index system for ventilation system safety is proposed based on the actual situation of coal mines.A comprehensive analysis is conducted on the existing ventilation problems,and corresponding optimization and transformation plans are proposed,and by comparing the comprehensive quantitative evaluation values of different optimization and renovation plans through the constructed indicator system,the best renovation plan is ultimately selected.
