Mechanism Analysis of Water-Filling Based on Material Properties in Jinjie Mine, NW China

Abstract:

This paper taking Jinjie Mine in northwest China as an example, on the basis of the hydrogeological analysis of the mineral deposit, explores the structure and influence factors of mine water inflow. The result shows that Jinjie Mine coal mining has destroyed the water-resisting roof layer, and then conducted the water channels. As a result, the original mode of hydrological cycle is changed, resulting in pore water, fissure water and surface water flow into the goaf through the water channel, and this help the water inflow be quite large (even reach 5380 m³/h). In order to coal mine safety production and protection of the areas fragile water environment, the curtain grouting technique using fly ash cement materials mainly is taken for preventing water.
