Near-horizontal thin ore body mining bottom plate fine ore recovery device and application method

Abstract

The embodiment of the invention discloses a near-horizontal thin ore body mining bottom plate fine ore recovery device and an application method, and belongs to the technical field of mining equipment. The device comprises a load trolley, wherein the load trolley comprises a load front part and a load back part; the load front part and the load back part are connected through a connecting component; the load front part comprises a front compartment; two front wheels are arranged under the front compartment; a hydraulic large arm fixing base is arranged on the front compartment; the hydraulic large arm fixing base is connected with a first hydraulic large arm; one end of the first hydraulic large arm is provided with a large arm linking bolt; the large arm linking bolt is connected with a second hydraulic large arm; a high-intensity steel wire brush roller is arranged under one end of the second hydraulic large arm; the load back part comprises a back compartment; two back wheels are arranged under the back compartment; and an engine power system and a cab are arranged on the back compartment. The mechanical equipment is used, so that the safe and reliable degree of the recovered fine ore can be improved; the national relevant safety production regulation is met; and the loss rate of a mine can be reduced, so that the economic benefits of the mine are improved.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and relates to a device and an application method for recovering fine ore from a mining floor of a near-horizontal thin ore body. Background technique [0002] When the existing near-horizontal thin ore body is mined by throwing blasting, it will be affected by factors such as rock clamping and ore rock stability, resulting in a large number of small lumps and powders left in the stope after the ore is mined. ore. Due to the very limited space of the stope, it is extremely difficult to recover this type of ore, which leads to an increase in the loss rate of the stope ore, which is not conducive to the economic development of mining enterprises. [0003] At present, the above-mentioned powder ore recovery technologies commonly used mainly include high-pressure water scouring, manual entry into the goaf, etc., and these recovery technologies have technical defects. Among them: high-press...
