Problems solved by technology

This technology is suitable for mines with very accurate and clear water guide channels and fissures, but usually the consumption of cement is large and the cost of water prevention and control is high
[0004] The above methods have played a certain positive role in the prevention and control of mine water inrush disasters, but each water control method is mainly carried out for specific hydrogeological conditions, and there are many limitations. Moreover, du...

Embodiment Construction

[0055] Below with reference to accompanying drawing, in conjunction with embodiment, a kind of underground water inrush dynamic comprehensive control method that combines dredging, blocking, exploration and monitoring provided by the present invention is described:

[0056] In a complex water-rich mining area, when the auxiliary shaft -245m was horizontally excavated from 2# to 8# to pass through the transportation lane, water inrush occurred, resulting in a well flooding accident, with a direct economic loss of more than 5 million yuan, and it took 18 months to deal with the accident construction time. The specific embodiment of the present invention is described for the governance process of the water inrush problem in this complex water-rich mining area. The flow of the underground water inrush dynamic comprehensive treatment method combined with dredging, blocking, exploration and monitoring of the present invention is as follows: figure 1 As shown, the specific implementa...

Abstract

The invention relates to the field of controlling underground water inrush disaster for mining projects and relates to a comprehensive treatment method of mine water inrush. The method includes the steps of setting a mine hydrogeology observation network; measuring a mine underwater supply area, a mine drainage area and a mine runoff area; exploring and measuring a water guide passage and fissures of the mine underwater supply area; determining and implementing a grouting curtain blocking scheme of the mine underwater supply area; designing and implementing a drainage treatment scheme of the mine drainage area, and after implementing the grouting curtain blocking scheme, performing underwater drainage treatment in the mine drainage area; implementing a scheme for dynamic monitoring of mine underwater level and information-based dredging and blocking treatment, during underwater drainage treatment in the mine drainage area, and dynamically monitoring the underwater level in the mine runoff area to finish the scheme.

Description

technical field [0001] The invention relates to the field of prevention and control of underground water inrush disasters in mining engineering, in particular to a dynamic comprehensive control method combining dredging, blocking, detection and monitoring of lateral surrounding rock water inrush in complex water-rich mining areas. Background technique [0002] Among the mineral deposits that have been explored and identified in my country, there are relatively large reserves that are difficult to exploit due to the threat of water inrush disasters. According to statistics, about 15 billion tons of coal deposits and 800 million tons of iron ore deposits are threatened by water inrush disasters. In the process of construction and mining of complex water-rich mines, there are always risks of water inrush caused by unfavorable factors such as interrelated complex hydrogeological conditions. A little carelessness in mining activities will induce water inrush accidents and cause ma...
