Description

Blast hole drainage device and using method thereof

Technical Field

The invention relates to the technical field of mine blasting exploitation, in particular to a blast hole drainage device and a using method thereof.

Background

Whether underground mining or open-pit mining, the perforation blasting technology is an essential link in the mining process. However, in the actual blasting mining process, after the mine is perforated, the phenomenon of water seepage in blast holes caused by underground water or rainfall in the open air is inevitable. After water is accumulated in the blast hole, when blasting and charging, on one hand, due to the buoyancy effect of the water, the explosive cannot be delivered to the bottom of the blast hole; on the other hand, the bottom of the blast hole is difficult to plug due to the existence of water, and the blast hole opening is difficult to plug after the charging is finished. Therefore, the blasting difficulty coefficient is increased due to the fact that the position of the explosive is unreasonable and the blast hole is not sealed well, so that the blasting effect is poor, the efficiency is low, for example, a plurality of blocks exist after blasting, and troubles are brought to subsequent transportation and ore dressing. Therefore, the accumulated water in the blast hole needs to be drained before blasting.

The blast hole drainage is carried out by means of a blast hole drainage device, and a common blast hole drainage device mainly utilizes a water pump to pump water or a piston type water pump to pump water. Although the degree of mechanization of the two drainage devices is high, the water pump or the water pump needs some power sources, such as electric power, when working, and the power sources can not be found under very difficult conditions, so that the application of the two drainage devices is limited. In addition, the water pump is easy to be blocked by sundries in the water pumping process. Therefore, the common blast hole drainage device consumes more manpower, material resources and financial resources, is more limited in use, has higher cost and is inconvenient to use.

The patent with the application number of CN201710122795.7 discloses a high-efficiency drainage device and a drainage method for blast holes, wherein the high-efficiency drainage device comprises a PVC pipe, the bottom of the PVC pipe is fixedly connected with a bottom one-way baffle, a water suction hole is formed in the bottom one-way baffle, and a movable circular baffle plate is arranged on the water suction hole; a round sealing movable baffle is arranged in the PVC pipe, a fastening hole is arranged in the middle of the upper end face of the round sealing movable baffle, and a rope is connected to the fastening hole. When the device works, if the water content in the blast hole is less, the water pressure is not enough to lift the circular baffle plate, a worker needs to pull up the circular sealing movable baffle plate on the upper part through a pull rope to form larger negative pressure in the PVC pipe, so that the circular baffle plate in the water absorption hole is lifted, and the water in the blast hole is absorbed into the drainage device. Although the device overcomes the defects that a common blast hole drainage device needs a power source and the like, the device has the disadvantages that (1) the water pumping operation is completed by pulling the rope completely by manpower under the condition of insufficient water pressure, the pulling-up process is laborious, and the PVC pipe is lifted up by manpower after being filled with water, a large amount of manpower is consumed, and the labor intensity of workers is high; (2) the internal diameter of PVC pipe is fixed, can't freely adjust the internal diameter of PVC pipe according to the aperture in big gun hole.

In view of the above, there is a need for an improved blast hole drainage device and a method for using the same to solve the above problems.
