Mine water disaster prevention and control device and method based on precipitation estimation

Abstract

The invention discloses a mine water disaster prevention and control device and method based on precipitation estimation, and belongs to the technical field of mine safety production. A mine water disaster prevention and control device based on precipitation estimation comprises a collecting barrel, a water receiving hopper and a water drainage pipe are arranged at the top and the bottom of the collecting barrel respectively, a filter screen is arranged on the outer wall of the water receiving hopper, a valve body is arranged on the water drainage pipe, and a partition block is arranged in the collecting barrel and divides the collecting barrel into a water inlet cavity and a water storage cavity. A circulation channel is arranged between the partition block and the inner wall of the collecting barrel, and the water inlet cavity communicates with the water storage cavity through the circulation channel. According to the invention, by arranging the drainage groove, external rainwater is drained during emptying operation of the water storage cavity, and the rainwater in the water storage cavity is emptied in an accelerated manner through the rapid emptying mechanism, so that the situation that the rainwater cannot be completely emptied can be avoided, and the precision of secondary detection is ensured, so that a worker accurately calculates the water inflow of a mine, and the working efficiency of the worker is improved. And mine drainage operation can be correctly guided.

Description

technical field [0001] The invention relates to the technical field of mine safety production, in particular to a mine water disaster prevention and control device and method based on precipitation estimation. Background technique [0002] The prevention and control of water in coal mines mainly follows the principle of "prevention first, combining prevention and control". Based on the investigation of hydrogeological conditions, measures should be taken according to local conditions. Blocking, there is a combination of dredging and blocking. At present, the prevention and control of mine water hazards often adopt methods such as setting water-proof coal pillars and releasing water in advance, resulting in waste of coal resources. The design of the height of water-proof coal pillars should be coordinated with seasonal rainfall in addition to referring to underground waterproof measures. The water source is complicated, and the Quaternary loose aquifer has a greater impact o...

Problems solved by technology

The instruments used in the direct measurement method can be siphon rain gauges, ultrasonic rain gauges, tipping bucket rain gauges, etc., but the above-mentioned equipment is prone to monitoring accuracy errors in the specific use process: the emptying process after the last round of timing detection However, the rainwater still continues to enter the water tank, which not only leads to low emptying efficiency, but also cannot effectively remove the rainwater, which will affect the next rainwater monitoring value, resulting in a larger detection value next time, and thus cannot effectively control the mining area. Accurate estimation of water volume makes it impossible to design a reasonable water control plan
