Abstract: In order to improve the technical level of water damage prevention for burnt rock , and reduce the occurrence of water hazard accidents in the Aai mining area of Xinjiang, the distribution characteristics and water richness characteristics of the aquifer in the burnt rock in the study area were introduced; Based on the relationship between the aquifer of burnt rock and the location of the mining area, the formation mechanism of water channels, and the direction of water inflow from burnt rock, the types of water damage caused by burnt rock in the study area were classified; Proposed the use of a combination of surface drainage and underground drainage for the prevention and control of water damage caused by burnt rock; We have studied the evaluation method for water hazard control effectiveness based on hydrophobicity, water level dynamic changes, and drilling verification, and selected typical working faces for application. The results showed that the water damage caused by the burnt rock in the Aai mining area can be divided into three categories: lateral water inrush from excavation disturbance cracks, water inrush from the top of mining induced cracks, and water inrush from the top of concentrated water channels; The cumulative drainage volume of burnt rock water in a typical working face was about 2.192 million cubic meters, and the average water level in the aquifer decreased by about 40 meters. Only 7.5m3/h of water gushed from the T1 hole outside the stop mining line of the working face, and there was no water in the remaining areas, indicating that the vast majority of the burnt rock water had been drained and the drainage effect was significant. The research results provide reference for the prevention and control of water damage caused by burnt rocks in the region.
