摘要
根据平煤二矿的矿井概况,在通风阻力测定路线的基础上,按照选点原则布置测点,利用气压计基点法,进行通风阻力测定。通过对数据的分析,得知主测路线上阻力测定相对误差满足矿井通风阻力测定和通风系统分析的精度要求;并得出西翼风井担负系统的回风段阻力所占比例过高和三水平风井担负系统三段通风阻力分布合理的结论,在此基础上找出了西翼风井担负系统回风段阻力过大的主要原因,进而提出加强管理维护,改变回风路线、进行通风系统优化等相应的降阻措施,为煤矿的安全管理提供依据。
Based on the determination of the ventilation resistance measurement line, according to the principle of selecting the measur- ing point of the mine, the ventilation resistance of the mine was determined by the method of the pressure gauge point method, based on the survey of the second mine of Ping Dingshan. After analysis, that the relative errors of the main route resistance determination meet the mine ventilation resistance determination and ventilation system analysis accuracy requirements; and know the ventilation difficulty degree was easy, and the mine west wing shaft shoulder system return section resistance proportion is too high, affect the ventilation machine work efficiency and causes a poor ventilation and st） on. , three horizontal shaft shoulder system three sections of ventilation re- sistance distribution is reasonable. On the basis of find out west wing shaft responsible system return section resistance on the main cause of, and then put forward strengthen the management and maintenance, to change the return route, optimization of ventilation sys- tem and corresponding measures for reducing resistance, and provide a basis for the management of coal mine safety.
