Coal mine underground reservoir residual storage capacity detection apparatus, detection equipment and detection method

Abstract

The invention discloses a coal mine underground reservoir residual storage capacity detection apparatus. The apparatus comprises fiber water level sensors, fiber displacement sensors, a data adapter box and computer equipment, wherein the fiber water level sensors and fiber displacement sensors are arranged at the bottoms of the auxiliary tunnels at the two sides of a reservoir base plate, the data adapter box is arranged in a main tunnel, the computer equipment is arranged outside the main tunnel, the plurality of water level sensors and fiber displacement sensors are arranged in each auxiliary tunnel at the two sides of the reservoir base plate, the plurality of water level sensors and the plurality of fiber displacement sensors are connected with the data adapter box respectively through optical cables, and the data adapter box is connected with the computer equipment through an overall optical cable. Disclosed are also coal mine underground reservoir residual storage capacity detection equipment and a detection method. The fiber displacement sensors and the fiber water level sensors are prearranged and a lowest water level and the elevation of each pit are calculated so that the residual storage capacity of a coal mine underground reservoir can be determined and safety risks of mining under the coal mine underground reservoir can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of application of coal mine underground reservoirs in mining engineering, in particular to a residual storage capacity detection device, detection equipment and detection method of coal mine underground reservoirs. Background technique [0002] As we all know, my country is a water-short country, and the shortage of water resources poses a serious threat to the development of the national economy and the improvement of people's lives. Mine water is unavoidable in the process of coal mining. The annual discharge of mine water by key state-owned coal mines alone is as high as 2.2 billion tons, and an average of 2 tons of waste water is discharged for every ton of coal mined. The discharge of mine water not only wastes a lot of precious water resources, but also easily constitutes serious environmental pollution to the surrounding environment. There are abundant coal resources in the western region of my count...

AI Technical Summary

Problems solved by technology

At the same time, due to the complex geological conditions of the coal mine, whether the water in the underground reservoir is empty and how much water cannot be discharged are important issues for the safe operation of distributed underground reservoirs in coal mines, and it is also a difficult problem that cannot be solved at present.

Due to the inability to determine the residual storage capacity of underground reservoirs in coal mines, the distributed underground reservoirs are not well utilized, which is not conducive to ensuring mine safety and avoiding water inrush accidents
