Mining and drilling combined unit for fully mechanized mining face and use method

Abstract

The invention discloses a mining and drilling combined unit for a fully mechanized mining face and a use method. The mining and drilling combined unit comprises a cutting coal mining part and a rock drilling part, wherein the cutting coal mining part comprises a left cutting rotary drum, a right cutting rotary drum, a left rocker arm, a right rocker arm, a left traction mechanism and a right traction mechanism; the rock drilling part comprises a left rock drilling mechanism and a right rock drilling mechanism; the rock drilling mechanisms are arranged at the tops of traction mechanism shells.The method comprises the following steps: putting a vertical column horizontally before coal mining work; starting the left and right cutting rotary drums, and keeping pushing the left and right cutting rotary drums forwards; in case of rocks, shutting down the cutting coal mining part, putting the vertical column upright, and fixing the vertical column; adjusting the height and horizontal and pitching angles of a rock drill; controlling a hydraulic lifting roof support to enable a pressing head to press a hydraulic bracket; starting the rock drill, and controlling a driving oil cylinder to work to crush rocks; readjusting the height and the horizontal and pitching angles of the rock drill to crush other parts of the rocks; after the rock crushing work is completed, and readjusting the rock drilling part to a state before the coal mining work is carried out to recover cutting coal mining work.

Description

technical field [0001] The invention belongs to the technical field of coal mine machinery, and in particular relates to a combined mining and drilling unit for a fully mechanized mining face and a use method thereof. Background technique [0002] At present, domestic coal mining generally adopts comprehensive mechanized mining methods, that is, coal shearers, hydraulic supports and scraper conveyors are used together. [0003] When the mining face encounters rocks such as pyrite concretions or hard gangue, it is necessary to take loose blasting measures to deal with it, and the shearer cannot be used to cut it forcibly, otherwise it is easy to cause damage to the shearer or generate sparks, which may cause gas Coal dust explosion accident. In order to restore the shearer to normal mining, it is usually necessary to withdraw the shearer first, then use special rock drilling rigs and other equipment to drill holes in the rock, and then perform blasting. [0004] Therefore, ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, in the traditional coal mining method, because the coal mining and rock drilling processes are separated from each other, it often leads to too long downtime of the shearer, which reduces the efficiency of the start-up of the shearer and the efficiency of coal mining.
