目前进行矿井通风阻力测定,主要有压差计法和气压计法两类方法。前者适用于精确测定局部巷道的通风阻力或摩擦阻力系数;后者适用于全矿性阻力测定,特别是在测定立井或人员不便进入铺设胶皮管和安放仪器的其它井巷的阻力时更具有优越性。利用气压计法(目前一般采用恒温气压计)测定矿井通风阻力时可采用两种测定方
Current mine ventilation resistance measurement, there are two main methods of pressure gauge and barometer method. The former is suitable for accurate determination of the local roadway ventilation resistance or frictional drag coefficient; the latter applies to all-mine resistance measurement, especially in the determination of shaft or personnel inconvenience into the laying of rubber pipe and other equipment placed in the wellway more superior resistance Sex. The use of barometer method (currently used constant temperature barometer) to determine the ventilation resistance of the mine can be used when the two measurement side
