Abstract

The invention relates to a coal mine semicircular arched roadway tunneling blast hole positioner and belongs to the field of mining equipment. The coal mine semicircular arched roadway tunneling blast hole positioner is provided with a plurality of lamp heads which are distributed in a ring-shaped array and a rectangular array. The underground working irradiation requirements are completely met, and safety and the reliability are realized; the ring-shaped array laser head is controlled by a connecting rod mechanism and an end head operation panel; the rectangular array laser head is controlled by a small-sized two-dimensional steering engine in a programmable manner, so that the precise unified operation of the lamp heads is realized; a linear laser light source working system is delicately applied, the devices of the steering engine, the step motor and the like are used for precisely controlling the rotary angle of the laser lamp head under the control of the controller, so that the underground blast hole distributing position precision is improved, the positioning work is simple, the positions of the loading blast holes are precisely guided and determined, the time consumption is short, the working efficiency is high, the labor intensity is small and the blasting effects are improved.

Description

technical field

[0001] The invention relates to a coal mine semi-circular arch roadway excavation blast hole locator, which belongs to the field of mining equipment. Background technique

[0002] The coal industry is one of the foundations of the country's existing industries, and as far as the current development of the country is concerned, coal mining is still dominated by underground mining. In the process of coal mining, the blasting and excavation of roadways and tunnels is one of the important links. The rationality and accuracy of the arrangement of charge holes in blasting and excavation directly affect the shape of the blasting roadway section, especially for smooth blasting. However, the traditional blast hole positioning is done by manual measurement. The positioning work is cumbersome and complicated, and the position of the charge blast hole cannot be accurately guided and determined. It takes a long time, has low work efficiency, high labor intensity, ...
