Monitoring and early warning method and system for coal mine underground reservoir coal pillar dam body structure

Abstract

The invention relates to a monitoring and early warning method and system for a coal mine underground reservoir coal pillar dam body structure, and relates to the technical field of coal mine underground reservoir safety monitoring. The invention provides a monitoring and early warning method. The method comprises the following steps: acquiring a monitoring signal of a coal pillar dam body; collecting and sorting the monitoring signals to obtain monitoring data and spatio-temporal information data; performing real-time inversion analysis on the monitoring data and the spatio-temporal information data; performing intelligent analysis on characteristics and rules of the monitoring data; and performing safety analysis on the coal pillar dam body structure according to the monitoring data, the spatio-temporal information data, the inversion analysis result and the intelligent analysis result. On the other hand, the invention provides a monitoring and early warning system. According to the monitoring and early warning method and system, data acquisition and analysis are carried out on the operation condition of the coal mine underground reservoir, real-time diagnosis and safety early warning of the coal pillar dam body are achieved, and a necessary decision basis is provided for reservoir optimization scheduling.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of coal mine underground reservoirs, in particular to a monitoring and early warning method and system for coal pillar dam structures of coal mine underground reservoirs. Background technique [0002] There are abundant coal resources in the western region of my country, but the lack of water resources has further aggravated the water shortage in mining areas and surrounding areas, which has seriously restricted the normal production of mining areas and is not conducive to the coordinated development of resources and the environment. For a long time, in response to the impact of coal mining on groundwater, a large number of technical research and engineering practices have been carried out at home and abroad: one is to try to prevent the generation of mine water, mainly using height limit and filling mining technologies; the other is to build water storage facilities on the ground ; The ...

AI Technical Summary

Problems solved by technology

Studies have shown that although filling mining and height-limit mining in the western mining area are technically feasible, they will greatly reduce the efficiency of coal mining and the recovery rate of coal resources, making it difficult to implement on a large scale; building water storage facilities on the ground will face difficulties in land acquisition and water resources. Technical problems such as evaporation waste and serious water pollution are also impossible to implement
