THE MINING INFLUENCE RESEARCH OF PRESSURE MINERAL IN LINEAR WATER CONSERVANCY PROJECT

With the mining of coal resources reducing gradually and the imperative of water conservancy project construction, pressed coal mining is inevitable. In the rational exploitation of pressure coal resources condition, how to ensure the safe operation of water conservancy facilities is an important realistic problem.This paper takes Chongqing Jinfo Mountain canal of conservancy engineering as an example, using subsidence MSPS system to analyze the surface subsidence data under pressure mineral mining. This paper researches its impact on the canal of linear water conservancy project according to the result, and puts forward the deformation treatment and control measures finally. Through the research on the results of Chongqing Jinfo Mountain canal conservancy engineering department, linear water conservancy project pressure mining on the influence of water conservancy project is significant, the effect refers to deformity caused by presssure mining, while the water flowing fractured and caving zone have little impact on linear water coservancy project. It can eliminate the surface subsidence hazard by reducing the settlement joint spacing and increasing the canal height.
