Abstract

The invention provides a coal mining device, and belongs to the technical field of coal mining. The coal mining device can comprise a walking part, a support part, a cutting part, an anchor rod / anchor cable drilling machine part, a top cutting drilling machine part and a collecting part. The support part can comprise a base, a lifting mechanism, a support and a front beam. The base can be fixed to the walking part, and the lifting mechanism can be fixed to the base and supports the support above the walking part. The front beam can be fixed to the support, and the cutting part can be arranged on the base and can stretch out towards the front portion of the walking part to cut an ore bed. The anchor rod / anchor cable drilling machine part can be arranged on the base and can stretch out towards the front portion of the support, and the top cutting drilling machine part can be installed on one side of the support part and can carry out directional joint cutting in a goaf. The collecting part can be connected to the base and can convey an ore body in front of the walking part to the rear portion of the walking part. According to the coal mining device, the aim of mining, anchoring and cutting integration is achieved, the working efficiency of coal mining can be greatly improved, and therefore manpower and cost can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of coal mining, in particular to a coal mining device. Background technique [0002] At present, the traditional coal mine 121 mining method is likely to cause problems such as waste of coal resources and low coal recovery rate. The N00 method of coal mining has been proposed in this field. The N00 method of coal mining is a coal mining method without tunneling and coal pillars. In the mining area of ​​the mine, the working face is self-mined and retained, realizing the integration of mining and realizing the mining of "N" working faces. In this method, the propulsion cylinder is installed to ensure the ventilation of the entire coal mining area, and when mining at each working face in the panel area, a part of the goaf is used to implement roof cutting and pressure relief for automatic roadway formation, and it is no longer necessary to excavate any tunnel roadway , It is no longer necessary to le...
