Method for determining capacity of underground reservoir of mine

Abstract

The invention discloses a method for determining capacity of an underground reservoir of a mine. The method includes steps of 1, measuring rock mass strength, coal seam buried depth and exploitation dimensions of the underground reservoir of the mine; 2, setting a reference underground reservoir of the mine with rock mass strength, coal seam buried depth and exploitation dimensions which are consistent with those of the to-be-measured underground reservoir of the mine; 3, measuring water storage capacity V2, reservoir area S and water head H of the reference underground reservoir of the mine and computing a water storage coefficient R according to the equation of R=V2 / SXH; and 4, measuring reservoir volume V1 of the to-be-measured reservoir of the mine and computing the capacity of the to-be-measured reservoir of the mine according to the equation of V=V1XR. By the aid of the method, the capacity of the underground reservoir of the mine can be obtained, so that water resources of a mining area can be regulated.

Description

technical field [0001] The invention relates to a method for determining the capacity of a reservoir, in particular to a method for determining the capacity of an underground reservoir in a mine. Background technique [0002] There are abundant coal resources in the west of our country, but the water resources are scarce. The shortage of water resources poses a serious threat to the economic development of the west and the improvement of people's lives. Mine water is produced during coal mining, and an average of 2 tons of waste water needs to be discharged for every ton of coal mined. However, at present, groundwater in mines is still mainly pumped to the ground. Due to seasonal factors such as water resources utilization, water resources are greatly consumed. Waste aggravates the imbalance of local supply. At the same time, most of the current treatment methods for mine water suspended solids and water quality are still mine water is discharged underground to the ground fo...

Problems solved by technology

Mine water is produced during coal mining, and an average of 2 tons of waste water needs to be discharged for every ton of coal mined. However, at present, groundwater in mines is still mainly pumped to the ground. Due to seasonal factors such as water resources utilization, water resources are greatly consumed. waste, exacerbating the imbalance of local supply, and at the same time, most of the current treatment methods for mine water suspended matter and water quality are still discharged from mine water to the ground for treatment, which is also likely to cause secondary pollution

Such technology further worsens the water shortage in the mining area and surrounding areas, seriously restricts the normal production of the mining area, and is not conducive to the coordinated development of resources and the environment

[0003] At present, there have been some attempts to protect groundwater resources, but these methods and technologies are all methods of purifying mine water through underground or ground treatment. For water-scarce areas such as the west, it is impossible to solve the problem of seasonal imbalance in water supply. At the same time, the loss of groundwater is not conducive to the restoration of the local ecological environment. The establishment of mine underground reservoirs is an important means to solve the problem of water use in mining areas and the imbalance of water use. Therefore, it is necessary to measure the storage capacity of mine underground reservoirs to rationally allocate mine groundwater resources.
