A drilling device for blasting and a method for cutting grooves in a mining house

Abstract

The invention discloses a method for cutting and forming grooves in a mining house and a drilling device for blasting, which belong to the field of mine blasting and drilling. In order to solve the problems of large volume and heavy weight of the above-mentioned blasting drilling vehicle, the problem of dead angle of drilling caused by the drilling rig fixed on the ground, and the safety problem of cutting the mine into grooves. The drilling device for blasting includes a trailer device and a drilling device. The trailer device includes a trailer seat, a wheel drive motor, wheels, a control box and a pull rod. The drilling device is placed on the trailer seat. The drill The hole device includes a mounting plate on which a number of mounting holes are arranged, and an auxiliary fixing device is installed in the mounting hole. The auxiliary fixing device includes an electric cylinder fixed through the mounting hole, and is fixed An auxiliary drilling motor is connected, and an auxiliary drill bit is fixedly connected to the rotating shaft of the auxiliary drilling motor. The invention greatly reduces the volume and reduces the weight, enables hand-held operation and stable drilling, and avoids the problem of drilling dead angles.

Description

technical field [0001] The invention relates to the technical field of blasting and drilling in mines, in particular to a method for forming cutting grooves in mines 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 using steel. The mining of iron ore is a hard job. With the development of society, iron ore mining has become more and more automated, which has relieved a lot of the burden on iron ore workers and made iron ore mining more convenient. [0003] In the process of iron ore mining and the process of cutting grooves into grooves in mine houses, it is often necessary to punch and blast the working face. This is a relatively heavy work. The workers hold the punching device to punch the ore layer. It will make the workers more tired. If the punching device is not supported, the punched holes will be unqualified, which will affect the blasting. ...

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 method of cutting grooves for mines is not safe enough, the present invention provides a cutting groove for mines The trough forming method and the drilling device for blasting greatly reduce the volume and reduce the weight, and can carry out hand-held operation and stable drilling, avoiding the problem of drilling dead angle, and improving the safety factor in the process of cutting troughs and forming troughs in the mining house
