One-time molding and segmented blasting method of inclined pass

Abstract

The invention provides a molding and blasting method of an inclined pass and a blasting drilling device, belongs to the field of mine blasting drilling, and solves the problems that a blasting and drilling vehicle is larger in size and heavier in weight, a drilling dead angle is caused by a drilling rig fixed on the ground, and the molding and blasting method of the inclined pass is lower in safety. The blasting drilling device comprises a trailer device and a drilling device; the trailer device comprises a trailer seat, wheel drive motors, wheels, a control box and a tie rod; the drilling device is placed on the trailer seat, and comprises a mounting plate; a plurality of mounting holes are formed in the mounting plate; an auxiliary fixing device is installed in each mounting hole; each auxiliary fixing device comprises an electric cylinder passing through the corresponding mounting hole to be fixed; auxiliary drilling motors are fixedly connected with the front ends of push rods of the electric cylinders; and auxiliary drill bits are fixedly connected to rotating shafts of the auxiliary drilling motors. The size and the weight are reduced greatly, hand-held operation and stable drilling can be performed, and the problem of the drilling dead angle is avoided.

Description

technical field [0001] The invention relates to the technical field of mine blasting and perforation, in particular to a one-time forming and segmented blasting method for an inclined chute and a drilling device for blasting. Background technique [0002] Introduction: Iron ore resources are a necessary material for social development. my country is a big country that uses steel. Iron ore mining is a hard job. With the development of society, iron ore mining has become more and more automated. It reduces a lot of burden and makes iron ore mining more convenient. [0003] During the mining process of iron ore and the forming and blasting process of the inclined chute, it is often necessary to drill holes and charge blasting on the working face. The workers are more tired. If they do not support the punching device, the holes punched will be unqualified, which will affect the blasting. At the same time, the distance between each hole needs to be measured. The whole process is ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned problems of large volume and heavy weight of the blasting drilling vehicle, the dead angle of drilling caused by the drilling rig fixed on the ground, and the existing blasting method for forming inclined chute is not safe enough, the present invention provides a blasting method for forming inclined chute and The drilling device for blasting greatly reduces the size and weight, and can improve the safety factor in the blasting process of the inclined chute
