Abstract:
In response to the problems of sudden water inrush accidents in fully mechanized mining faces, the lagging response of traditional drainage systems, and the cumbersome deployment that can lead to the spread of disasters, this paper designs and develops a set of efficient emergency drainage devices. This device integrates three core modules: adaptive water accumulation monitoring, high-head and high-flow drainage, and mobile adaptive installation, to build an integrated emergency response system of “real-time monitoring - intelligent early warning - rapid response”. Among them, the water accumulation monitoring module uses a distributed sensor network (including liquid level and flow sensors), which can accurately capture water conditions in the early stage of water inrush and trigger automatic early warning, achieving millisecond-level linkage with the drainage system; the drainage module is equipped with a double-stage centrifugal pump group (single pump head ≥ 80 m, flow ≥ 200 m
3/h), and is combined with a quick-disassembly anti-corrosion pipeline interface, which can not only meet the high-intensity drainage requirements but also achieve rapid pipeline connection within 3 minutes; the mobile adaptive module innovatively utilizes the existing scraper conveyor tracks and hydraulic support bases in the working face to design a sliding installation frame, which can complete the device positioning without additional excavation of the foundation, significantly enhancing the deployment flexibility in complex working conditions. Field application verification shows that the response time from the start-up to the drainage of this device is ≤ 3 minutes, with an efficiency improvement of more than 50% compared to traditional emergency drainage equipment, and can control the water accumulation rise rate in a short time. Its application effectively buys critical time for the evacuation of underground personnel, reduces the damage of water accumulation to equipment and roadways, and has important practical significance in curbing the expansion of water disasters, ensuring the safety of miners’ lives, and accelerating post-disaster production recovery.
