Safe monitoring method for mine underground reservoir

Abstract

The invention discloses a safe monitoring method for a mine underground reservoir, comprising the following steps of: (1), acquiring the compression strength and the permeability parameter of mine underground reservoir rock mass; (2) selecting the position where the compression strength is less than a compression strength set value as a first safe monitoring point, and selecting the position where the permeability parameter is greater than a permeability parameter set value as a second safe monitoring point; (3), setting a pressure sensor for detecting the rock mass stress and a permeability sensor for detecting the permeability parameter on the first safe monitoring point and the second safe monitoring point respectively; and (4), giving out an alarm when the permeability parameter of the detected rock mass reaches a permeability parameter alarm value or the rock mass stress reaches the compression strength set value. The sensors are arranged on the rock mass of the mine underground reservoir, the dynamic real-time monitoring of the compression resistance and the permeability resistance of the underground reservoir can be realized, the potential safety hazard can be eliminated, and the inrush accident can be effectively avoided, so that the safe and stable running of the mine underground reservoir can be guaranteed.

Description

technical field [0001] The invention relates to a safety monitoring method, in particular to a safety monitoring method of a mine underground reservoir. 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 for treatment, and it is easy to cause second...

AI Technical Summary

Problems solved by technology

However, when the underground reservoir stores excessive groundwater, the water pressure will increase. When the water pressure exceeds the water resistance capacity of the rock mass of the underground reservoir, water-conducting cracks will be formed in the rock mass, resulting in a water inrush safety accident. Therefore, it is necessary Carry out safety monitoring on mine underground reservoirs to rationally allocate mine groundwater resources
