Stringing scheme and required drainage cell quantity；
(2) according to design requirement, discharge pipe line is arranged in pit shaft, each submersible sewage pump is transported in pit shaft simultaneously and is pacified
Dress is fixed, and connects discharge pipe line and combines each drainage cell formation drainage system；
(3) after waiting each drainage cell ready, with jet vacuum pump, air in submersible sewage pump and drainage pipeline is extracted out, utilize
High-speed jet pumping in compressed air and discharge pipe line starts submersible sewage pump；
(4) connect the power supply of each drainage cell, run submersible sewage pump, the waterflooding in pit shaft is passed through discharge pipe line pump drainage to ground
Face.
The beneficial effects of the utility model are as follows：
With the contrast of conventional emergency drainage method, using this combined water-drainage drainage, mine " empty gushing water always " disaster is flooded
Aqua region carries out disaster relief draining and has following characteristics and advantage：
(1) use this drainage and exhaust system and method, build by the way of serial or parallel connection combines multiple drainage cells
Drainage and exhaust system, can meet the dewatering needs under various difference operating modes, be with a wide range of applications；
(2) this drainage and exhaust system and method are used, selecting can be with the husky small-sized submersible sewage pump composition draining of draining coal, spoil disposal
Unit, also possesses stronger pollution discharge capability while draining, can pump drainage silt and larger " always empty prominent of coal slurry content well
Water " disaster waterflooding；
(3) use this drainage and exhaust system and method, system is divided into some drainage cells to carry out assembling simultaneously and runs, fortune
Defeated simple and convenient, there is stronger mobility, the set-up time of equipment can be greatlyd save simultaneously, be the fast of mine water bursting disaster
Speed rescue offer condition.
