Embodiment Construction

[0037] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0038] Such as figure 1As shown, the mining rock mass seepage water outburst method of the present invention is characterized in that it first analyzes the distribution of the structural key layers and aquifers in the stope affected by the mining, and then determines the mining area. The position of the main water-proof key layer of the field; during the mining process, use the microseismic monitoring system to remotely monitor whether the main water-proof key layer of the roof and floor of the stope is affected by mining to produce water-conducting crack channels, and abnormal signals indicate that there are cracks If the location of the abnormal signal is located at the position of the main water-resistant key layer, it means that the water-conducting crack is generated. In the mining rock mass roof and floor area, mine geological radar is used to detect t...

Abstract

The invention discloses a mining rock mass water seepage and inrush near and near multi-source grading information intelligent monitoring and early warning method, and belongs to the field of water-preserved mining and remote sensing rock mechanics. In the mining process, a micro-seismic monitoring system, a mining geological radar monitoring system and an infrared radiation monitoring system are used in a combined mode to conduct monitoring and graded early warning on the water seepage and inrush conditions at the near and near three spatial positions of a mining rock mass, and multi-source information graded early warning indexes and corresponding judgment threshold values are determined; meanwhile, collecting and sampling water inrush in a roof and floor surface monitoring area, a water inrush water source is analyzed, and whether water flowing fractures of aquifers of a roof and a floor are communicated or not is judged auxiliary. A mining rock mass water seepage and inrush near and near multi-source information real-time grading information intelligent monitoring and early warning system is formed. According to the mining rock mass water seepage and inrush near and near multi-source grading information intelligent monitoring and early warning method, the monitoring and early warning precision of water seepage and inrush and coal and rock mass stability in the excavation process can be improved, and a foundation is laid for water-preserved mining and safe and efficient mining of mines.

Description

technical field [0001] The invention relates to an intelligent monitoring and early warning method for seepage water inrush in mining rock mass, which is far and near, multi-source classification information, and belongs to the field of water conservation mining and remote sensing rock mechanics. Background technique [0002] As the demand for coal resources increases and the scale of coal production continues to expand, coal mine seepage and water inrush disasters not only cause serious casualties and economic losses, but also lead to groundwater pollution and loss, causing irreversible damage to the environment. It is an important issue restricting the safe and efficient production of coal mines. [0003] With the rapid development of coal production towards intensification and scale, the prevention and control of water inrush disasters in coal mines not only needs to control the deformation and crack development of mining rock mass in the stope, but also requires real-tim...
