The invention relates to the technical field of coal mine water disaster prevention and control, and discloses a grouting device for coal mine water disaster prevention and control. The grouting device for coal mine water disaster prevention and control comprises a bottom plate, wherein supporting columns are fixedly mounted on two sides of the top of the bottom plate, a top plate is fixedly mounted on the tops of the supporting columns, and a lifting motor is fixedly mounted on the top of the top plate; a screw rod is fixedly mounted at the top of an output shaft of the lifting motor, a nut is in threaded connection with the outer wall of the screw rod and fixedly mounted in a lifting plate, and the lifting motor operates to drive the lifting plate and a grouting cylinder to descend through transmission of the screw rod and the nut, so that the grouting cylinder penetrates into a ground hole; a driving motor runs to drive a rotating shaft, a connecting column and a soil loosening auger to rotate through transmission of a worm gear and a worm, the soil loosening auger rotates to loosen a rock-soil body below the grouting cylinder, sinking of the grouting cylinder is facilitated, and the grouting cylinder cannot be blocked by the hard rock-soil body. The grouting device for coal mine water disaster prevention and control has the advantages of being convenient to drill into ground pores, uniform in grouting and large in grouting force.
Description
technical field [0001] The invention relates to the technical field of coal mine water disaster prevention and control, in particular to a grouting device for coal mine water disaster prevention and control. Background technique [0002] Coal mine floods affect the progress and quality of mine construction, worsen the working environment of workers, increase the drainage facilities and drainage costs of mines, and bring unsafe factors to coal mine production. In severe cases, well flooding accidents even occur, causing major loss of life and property. loss. In the process of coal mining, it is very easy to communicate with old kiln water accumulation, water leakage accidents in car-making mines, and coal mine water damage accidents will also lead to erosion and weakening of surrounding rocks and induce secondary disasters. The hydrogeological conditions of my country's coalfields are complex, and currently about 80% of the coal reserves to be mined are threatened by relativ...
