江西下垄钨矿巧用空吸作用原理,引水下矿井,每年为国家节省开支一万一千余元。该矿大部分为井下深部开拓,竖井提升的开采方式。采场都在地下一二百米深处。由于井口水源水位低,窿内用水全由水泵输送,分段作业,每天仅一个中段输水耗电二百八十多度。他们根据140中段距河道近,井筒深的特点,大胆革新,利用管路中的水在竖井作加速度流动能产生吸力的原理,安装 Jiangxi Xiandu Tungsten mine clever use of the role of suction principle, diversion under the mine, annual savings of more than 11,000 yuan for the country. Most of the mine for deep underground exploration, shaft to enhance the mining method. Stope are in the ground one hundred two hundred meters deep. Due to the low water level of the wellhead, all the water in the hole is transported by the pump, and the work is carried out in stages. Only one middle section of the well consumes more than 280 degrees of water per day. According to the middle of the 140 middle of the river, the characteristics of deep wellbore, bold innovation, the use of pipe in the shaft for acceleration flow of water can produce suction principle, the installation
