Abstract
The invention relates to a draining method capable of preventing underground mine inrush water flooding accidents. A primary drainage system is arranged at the bottom of a well; a secondary drainage system is arranged in the middle section of the upper part not exceeding a low-pressure power supply effective distance; the primary system is provided with three diving pumps of the same specification; a drainage pipe of each diving pump, a sealing power line and a sensing line lead to the secondary system; a power supply and distribution mechanism and a master control mechanism are arranged in the secondary system; when the primary system is submerged, the master control mechanism of the secondary system controls the diving pumps of the primary system to work normally, so the whole drainage system under the well can be self-rescued; and when the depth of a mine is smaller than the allowable distance of low-pressure power supply, only the primary drainage system is provided, so that the power supply and distribution mechanism and the master control mechanism are arranged on the earth surface.
Description
Technical field
The invention belongs to mine technology field
Background technology
At present both at home and abroad without similar technology report; Each mine is all the water discharge method of carrying out GB16423-2006 " metal and nonmetal mine safety code " regulation: " outlet of the main pump house in shaft bottom should be no less than two, and one of them leads to shaft station, and its outlet should be installed water door; Another is communicated with pit shaft with inclined gallery, inclined gallery are suitable for reading should exceed pump house ground level 7m more than "; The method can only be taken precautions against less water inrush accident, exceedes 7 meters once gushing water floods the roadway degree of depth, and the whole drainage system in down-hole will all be paralysed; The object of the invention is to adopt new water discharge method, when water inrush and inundate mine accident is occurred, shaft bottom drainage can not be paralysed, and still can utilize existing drainage system to realize and save oneself.
Summary of the invention
Shaft bottom arranges one-level drainage system, in the stage casing, top of low-voltage power supply coverage, secondary drainage system is set again; One level system arranges three same specification submersible pumps, and the gutter of every submersible pump and sealed motive force line, sense line all lead to level two, is located at level two for distribution and master control mechanism; For convenience of operation and repair and maintenance, separately draw three signal line to a level system from level two, make the button of a level system can control under normal circumstances submersible pump start-stop, but the master control mechanism of level two should be able to abrogate and recover the start-stop button of a level system; In the time that a level system floods, normally worked by level two master control mechanism operating one level system submersible pump; Owing to increasing the corresponding increase of drain discharge of submersible pump with depth of immersion, down-hole entirety drainage system can be realized and save oneself; The mine degree of depth be less than low-voltage power supply license apart from time, only establish one-level drainage system, be located at earth's surface for distribution and master control mechanism; All the other sump, pump house, the selection of pump technology parameter etc. are carried out by design specifications.
Claims (1)
1. a water discharge method for capable of preventing underground mine inrush water flooding accidents, is characterized in that: shaft bottom arranges one-level drainage system; Stage casing, top at low-voltage power supply coverage arranges secondary drainage system again; One-level drainage system arranges three same specification submersible pumps, and the gutter of every submersible pump and sealed motive force line, sense line all lead to secondary drainage system, is located at secondary drainage system for distribution and master control mechanism; In the time that one-level drainage system floods, normally worked by the submersible pump of secondary drainage system master control mechanism operating one-level drainage system; For convenience of operation and repair and maintenance, separately draw three bars cables to one-level drainage system from secondary drainage system, make the button of one-level drainage system pump house can control under normal circumstances submersible pump start-stop, but the master control mechanism of secondary drainage system should be able to abrogate and recover the start-stop button of one-level drainage system; The mine degree of depth be less than low-voltage power supply license apart from time, only establish one-level drainage system, be located at earth's surface for distribution and master control mechanism.
