Abstract

The invention provides a method for designing a gas storage cavern in a goaf combining a curtain and a water curtain, which includes the following steps: S1: According to the mining data of the mine and the detailed geological survey data, delineate the underground gas storage for storing natural gas area; S2: set multiple roadways above the underground gas storage area; S3: drill multiple grouting holes and water curtain holes in the surrounding rock in the roadway, and pass through the water curtain holes and The grouting hole injects water and grouting into the surrounding surrounding rocks to form a water curtain and a curtain to seal the underground gas storage area. The present invention establishes curtain and water curtain system, grouting reinforces the surrounding rock, and fills pores and fissures to reduce seepage flow and seepage pressure; water curtain holes form a water curtain system to reinforce and seal the natural gas storage area, preventing natural gas from diffusing to the surroundings, Leakage, to ensure the safety of underground gas storage in mines.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a design method of a goaf gas storage cavern combining a curtain and a water curtain. Background technique [0002] my country is the country with the most abundant coal resources, and coal still occupies an absolute position in my country's primary energy structure. During the coal mining process, a series of roadways or chambers need to be excavated. The mining roadway will be destroyed with the completion of the mining work, while the preparation roadway and the development roadway will remain deep in the formation after the mining work is completed. With the cessation of maintenance work And become permanently abandoned underground space, spend a lot of money and manpower to build the underground chamber can not be fully utilized. [0003] With the increasing pressure of environmental protection and technological progress, the low-carbon trend of energy consu...
