Background
The ore pass system is the throat of an underground mine transportation system and plays an important role in the production process of mines. In order to realize the transfer of the ores and the waste rocks, a series of orepasses are constructed in a mine development system, and particularly, a main orepass is constructed near a main lifting system to realize the transfer function of the ores and the waste rocks. However, in the production process, due to the influence of various factors such as rough wall surfaces of the chute, ore accumulation, existence of large long-strip-shaped blocks, overlong slag accumulation time and the like, the chute often has phenomena such as arching, blockage and the like, the mine production is seriously influenced, and even the production stop phenomenon occurs in the subsequent ore dressing link.

However, the method has great detection difficulty, so that a reasonable medicine feeding position and angle are often found by a method of drilling a plurality of blast holes, and the blockage is often exploded by a plurality of times of blasting. Therefore, the method is complicated to operate and low in efficiency.
The mode of the water filling dredging method is that water is filled into a shaft of the chute from the upper part of the chute, the friction force between material blocks is reduced by wetting the materials by the water, and finally the materials are blocked by arching in the chute and fall under the action of self gravity, so that the aim of dredging the chute is fulfilled. However, the method has a plurality of problems in operation, and the following potential safety production hazards of mines are easily caused: firstly, when water is poured into the chute, the water pouring amount cannot be controlled, the water amount is too small, arch formation or blocking materials cannot fall, and the purpose of dredging the chute cannot be achieved; secondly, the irrigation quantity is too large, so that a debris flow is easily formed, the influence on structures, facilities and personnel at the lower part of the chute is caused, and the personal safety is also greatly threatened; thirdly, the dredging time of the ore pass cannot be determined, which is not beneficial to the normal organization of mine production.

step six, remote control operation: according to the infrared distance measurement value in the display screen (16), the wireless remote controller (17) sprays water flow to the outer side water spray opening (12) by controlling the horizontal direction, the explosive loading platform (2) is adjusted at the central position of the cross section of the draw shaft, and the explosive loading platform (2) is slowly lifted upwards and lifted to the vicinity of the lower surface of ore blocked by the draw shaft by controlling the downward water spray opening (11) to spray water flow downwards, so that the explosive package (6) on the explosive loading platform (2) is tightly attached to the lower surface of the blocked ore;
step seven, connecting wires and detonating: and (3) connecting the external detonating tube leg wire (7) of the detonator to a detonating network, and detonating the explosive package (6) to realize blasting and dredging the blockage of the chute.
10. The method of claim 9 for blasting orepass plugging, wherein: the concrete process of debugging the water pressure of the water pipe in the fifth step is as follows: the pressure is gradually increased through a manual valve on a high-pressure water steel pipe interface, and the pressure is adjusted to be equal to the sum of the gravity of the explosive loading platform (2), the loading platform chassis (9), the explosive bag (6), the detonating tube detonator (21) and the high-pressure water pipe (15), so that the suspension state of the blasting device is ensured.
