Embodiment Construction

[0030] see figure 1 with 2 , showing the method of the present invention for constructing a coal mine connected underground reservoir by using bedrock curved belts.

[0031] The technical problems that need to be solved in the method of constructing coal mine connected underground reservoirs by using bedrock curved belts include: for the proposed construction area of ​​underground reservoirs, it is necessary to carry out research including stratum lithology, geological structure, and spatial scope (using previous exploration data collection, field reconnaissance, and comprehensive verification of geophysical drilling), focusing on the detection of bedrock roof (reservoir floor) water resistance, Quaternary strata water storage and water conduction capacity; combined with the coal mine surface drainage system and water supply system, to achieve The optimal transportation of mine water to underground reservoirs determines the reasonable construction site of underground reservoi...

Abstract

The invention relates to a method for constructing a coal mine connected underground reservoir by using bedrock curved belt, which comprises the following steps: step 1: exploration of geological conditions for building an underground reservoir in bedrock curved belt; step 2: optional underground reservoir in bedrock curved belt The construction address is determined; step 3: the connectivity construction of the connected underground reservoir in the bedrock curved zone; step 4: the construction of the mine water transportation, recharging and extraction system; Based on the analysis of the conditions, based on the site selection of the traditional coal mine underground reservoir construction, the overall design of the coal mine connected underground reservoir using the bedrock bending zone is proposed to reduce the ineffective discharge of mine water resources, avoid the waste of water resources, and make full use of The curved belt formed by mining is used to build underground reservoirs to reduce engineering construction costs. Ultimately realize the maximum protection of mine water resources in underground coal mines in arid areas.

Description

technical field [0001] The invention relates to the technical field of comprehensive application of water conservancy engineering, hydrogeology and mining engineering, and in particular to a method for constructing a coal mine connected underground reservoir by using bedrock curved belts. Background technique [0002] First of all, during the mining process of underground coal mines, since the water-conducting fracture zone has developed to the upper aquifer, the aquifer water enters the goaf. In order to ensure the safety of coal mining, mine water must be discharged. A large amount of mine water resources are pumped to the ground, resulting in a waste of water resources. [0003] Secondly, my country's water resources and coal resources are distributed in reverse. The 14 large coal bases are mainly located in arid areas such as the Northwest and Northeast, and the evaporation is 4 to 6 times that of the precipitation. Can not be effectively stored and utilized. [0004] T...
