Comprehensive treatment method of mine water inrush

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...

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, due to the close hydraulic connection between mines and regional groundwater In the case of complex hydrogeological conditions and water inrush channels in mining areas, variable types of water inrush in ore deposits, and large water inrush volumes, it is usually difficult to achieve the expected effect of water inrush prevention and control by using a single drainage or plugging treatment plan, and the technical High requirements for conditions and economic costs
