Problems solved by technology

[0004] In view of the mine’s existing ore body, the thickness of the ultra-thin veins is less than 0.8m, and traditional rock drilling tools cannot operate in this space, so the operating space must be expanded, which must increase the amount of wall cutting work, resulting in increased production costs

Abstract

The invention belongs to the technical field of novel rock-drilling devices for extreme-thin ore layers and particularly relates to a rock-drilling carriage assembly device which is assembled of rock-drilling support researched by means of air legs as a pushing device of an electric coal drill. The rock-drilling carriage assembly device includes a group of electric drill racks which are fixedly connected through a lifting support to each other. A jack is arranged in the lifting support. The lower end of the lifting support is connected to a sliding guide rail so that the lifting support can be moved on the sliding guide rail back-and-forth. The electric coal drill in the same direction is arranged on the electric drill racks. The rock-drilling carriage assembly device not only solves the problems of insufficient spaces of water supplement, gas supplement and operations which are insoluble in a down-hole local working plane, but also is greatly reduced in unit consumption of electricity in mining.

Description

technical field [0001] The invention belongs to the technical field of new rock drilling equipment for extremely thin ore bodies, and in particular relates to a rock drilling rig combination device composed of a rock drilling bracket developed by using an air leg as a propulsion device of a coal electric drill. Background technique [0002] In the mining of gently inclined thin ore bodies, because the mining technology is limited by geological conditions, the development is relatively slow. Since self-slipping cannot be realized, and the degree of mechanization is generally considered to be limited by the environment, it is considered to be a difficult-to-mine ore body. The main mining method is wall cutting and filling mining. These methods are mainly suitable for high-grade ore, extremely thin precious metal or rare metal deposits, and deposits attached to other minerals. The essence of this method is that in mining, in order to ensure the width or height of the working f...
