Assembly method of vacuum drainage system for mine shaft

Abstract

Provided is an assembly method of a vacuum drainage system for a mine shaft. The vacuum drainage system is composed of a cement pit, a perforated strainer, a support, an inductor, a water level alarm, control valves, a vacuum water pumping pipe, a vacuum box, a top board, vacuum pumps, air suction ports, a liquid level indicator, a vacuometer, a water inlet bent pipe, a drainage pipe and a controller. The support is installed at the bottom of the cement pit in the mine shaft, the vacuum water pumping pipe is installed on the support, and the perforated strainer is installed above the cement pit; the vacuum box is installed on the ground, the top board is installed above the vacuum box, and the top board and the vacuum box are installed oppositely; the vacuum pumps are installed on two sides of the upper side of the top board, and the controller is installed on one side of the vacuum box. The assembly method resolves the technical problem that the suction stroke of a water pump in an existing drainage device is insufficient, can achieve complete drainage of accumulated water in an underground water bin of a deep mine, reduces consumption of electric energy, improves the utilization rate of the water pump, reduces maintenance costs of the water pump, guarantees safety in production, and effectively resolves the problems that the suction stroke of the water pump is limited and water leakage accidents and water inrush accidents occur.

Description

technical field [0001] The invention relates to the technical field of mine drainage, in particular to a method for assembling a vacuum drainage system for mines. [0002] Background technique [0003] At present, in the underground mining process, a large amount of groundwater often gushes out. Generally, the large amount of groundwater flows into the underground water tank in a natural flow through the drainage ditch, and then collects the water through the drainage device of the tank. Drain to the ground, due to the short suction of the water pump used in the drainage device, the water tank will not be designed too deep, the suction of the water pump is limited, and the water cannot be drained. Water must be pumped at any time during "peak, valley, and flat", which will increase electricity consumption and increase mining costs.

Problems solved by technology

[0003] At present, in the underground mining process, a large amount of groundwater often gushes out. Generally, the large amount of groundwater flows into the underground water tank in a natural flow through the drainage ditch, and then collects the water through the drainage device of the tank. Drain to the ground, due to the short suction of the water pump used in the drainage device, the water tank will not be designed too deep, the suction of the water pump is limited, and the water cannot be drained. Water must be pumped at any time during "peak, valley, and flat", which will increase electricity consumption and increase mining costs. Once water leakage occurs in the underground mining area, due to insufficient water storage capacity, there will be no more The time for workers to escape is extremely prone to casualties

[0004] The patent document with the application number of 87200749.9 discloses a compressed air mine drainage device, which has a small displacement, complicated structure installation, and slow drainage speed. Once a water leakage accident occurs, it is difficult to drain water in time.
