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 the mine technology field
Background technology
No similar techniques is reported both at home and abroad at present; Each mine all is a water discharge method of carrying out GB16423-2006 " metal and nonmetal mine safety rules " regulation: " outlet of the main pump house in shaft bottom should be no less than two, and one of them leads to the shaft station, and its outlet should be installed water door; Another is communicated with pit shaft with inclined gallery, and inclined gallery are suitable for reading should to be exceeded more than the pump house ground level 7m "; This method can only be taken precautions against less gushing water accident, surpasses 7 meters in case gushing water floods the roadway degree of depth, and the down-hole whole drainage system will all be paralysed; The objective of the invention is to adopt new water discharge method, when prominent watered-out well accident was taken place, the shaft bottom drainage can not paralysed, and still can utilize existing drainage system to realize saving oneself.
Summary of the invention
Subject content is: the shaft bottom is provided with the one-level drainage system, in the stage casing, top that is no more than the low-voltage power supply coverage secondary drainage system is set again; One level system is provided with three same specification submersible pumps, and the gutter of every submersible pump and sealed motive force line, sense line all lead to level two, supplies distribution and master control mechanism to be located at level two; Be handled easily and repair and maintenance, draw three signal line in addition to a level system, make the button of a level system under normal circumstances can control the 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 from level two; When a level system floods, by level two master control mechanism operating one level system submersible pump operate as normal; Be multiplied owing to increase the drain discharge of submersible pump with depth of immersion, make the whole drainage system in down-hole can realize saving oneself; The mine degree of depth less than low-voltage power supply permission apart from the time, only establish the one-level drainage system, supply distribution and master control mechanism to be located at the face of land; All the other sump, pump house, the selection of pump technology parameter etc. are carried out by design specifications.
Claims (1)
1. a way of taking precautions against the water discharge method of the prominent watered-out well accident of underground mine is:
The shaft bottom is provided with the one-level drainage system; Stage casing, top being no more than the low-voltage power supply coverage is provided with secondary drainage system again; One level system is provided with three same specification submersible pumps, and the gutter of every submersible pump and sealed motive force line, sense line all lead to level two, supplies distribution and master control mechanism to be located at level two; When a level system floods, by the submersible pump operate as normal of level two master control mechanism operating one level system; Be handled easily and repair and maintenance; Draw three bars cables in addition to a level system from level two; Make the button of one-level system pump house under normal circumstances can control the 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; The mine degree of depth less than low-voltage power supply permission apart from the time, only establish the one-level drainage system, supply distribution and master control mechanism to be located at the face of land.
