Description
Technical Field
The invention belongs to the technical field of mine drilling, and particularly relates to a blast hole blockage treatment device and method.
Background
In the process of mining underground ore bodies by using a drilling and blasting method, the construction quality of blast holes determines the difficulty of subsequent charging work and the final blasting effect. Due to the influence of rock crushing and adjacent blast hole blasting, the blast holes are blocked due to frequent rock wall stripping of the constructed blast holes, and the situation is particularly obvious under the action of high stress or in the rock self-joint and crack development areas. If the blocked blast hole is not dredged in time, the problems of insufficient explosive loading and uneven explosive distribution easily occur in the subsequent explosive loading construction process, the designed blasting position is not exploded, the large block rate of the blasting pile is high and the like, the processing work of the unexploded area is carried out under an empty field, the great potential safety hazard exists, and meanwhile, the final mining cost is increased by massive secondary blasting.
The invention discloses a conveying device for a blast hole measuring pipe, which aims at the defects of the existing blast hole measuring method. Aiming at a laser measurement method, the requirement on the positioning accuracy of the center of a blast hole is particularly high, the designed diameter of the blast hole is 86mm, the depth is about 20m, and the deviation can cause that the laser distance measurement method cannot measure the bottom of the hole, so that the depth value of the bottom of the hole cannot be read. The other method is a sound wave distance measuring method, because of the influence of disturbance noise and the like in underground mine construction, the sound wave transmitting frequency needs to be adjusted to be the maximum when the sound wave distance is measured, a blind area can be enlarged, a plurality of echo values are caused by the concave and convex uneven wall of a blast hole, which echo value is difficult to determine is a hole bottom echo, so that the two existing hole measuring methods are difficult to accurately measure the depth of all the blast holes, according to the data measured on site, about over thirty percent of blast holes can not measure accurate depth values, and whether the blast holes are blocked can be determined only by manually conveying a measuring pipeline, and can't carry out the big gun hole and block up the condition and handle, artifical measuring mode is that alone takes a diameter to be about 40 mm's stand pipe to stretch into the big gun hole and leads, and another person takes a metal hard tube to stretch to the big gun hole bottom along the stand pipe always, still need carry alone in addition and survey the buret, and big gun hole blocks up work efficiency low, and intensity of labour is big, is unfavorable for carrying out smoothly of measurement work. The underground mine has complex environment, the electric device is not convenient to operate, and the mechanical device is more convenient.
For example: CN202022247280.X discloses a blast hole dredger for open-air deep hole blasting, which comprises a dredger comprising a dredging part and a handle, wherein the handle is fixedly connected to one end of the dredging part, and a spiral blade is fixedly connected to the circumferential surface of one end, away from the handle, of the dredging part; one end with spiral leaf mediation piece stretches into the end of big gun hole, twist grip, and the spiral leaf rotates and stirs rock or rock powder in the big gun hole, and rock or rock powder move towards the direction of being close to the handle along with the rotation of spiral leaf, pull out mediation piece towards the direction of being close to big gun drill way afterwards, and rock or rock powder are also cleared up out. Above-mentioned patent is to the strip mine to be not suitable for on the underground mine to fan-shaped big gun hole and block up processing apparatus and use, underground mine big gun hole aperture diameter 86mm, the aperture is less, and above-mentioned big gun hole dredge can't stretch into the big gun hole, and the device structure is complicated, is unfavorable for underground mine big gun hole and blocks up processing apparatus and use.
For another example, the utility model CN201821112495.7 discloses a convenient and fast tool for dredging the blast hole, which comprises a dredging rod, wherein a double-hook tool is arranged in a cavity inside the dredging rod, the double-hook tool is formed by arranging two round rods with clamping parts at the front ends in a staggered manner, and fulcrum shafts are arranged at the staggered positions, so that the two round rods can be opened and closed relatively; the tail end of the double-hook tool extends out of the tail end of the dredging rod; the distance from the staggered part of the two round rods to the front end of the round rod is 1/12-1/10 of the total length of the round rod. The blast hole dredging tool with the structure can quickly and conveniently dredge a blast hole, and can quickly clean slag in the blast hole when the blast hole needs to be cleaned, so that manpower and material resources are greatly saved, and the tool is simple in design and convenient to use. However, the blast hole dredging tool aims at the underground blast hole dredging in the mining area, can realize the smooth loading of the emulsion explosive into the eye ground, clear up all slag in the blast hole, can quickly draw out the hole and smoothly charge the explosive, is not suitable for a treatment device for blocking the upward fan-shaped blast hole in the underground mine and the use thereof, and cannot achieve the purpose of through hole.
