Autonomous walking mechanism of deep coal fluidized mining equipment

Abstract

The invention discloses an autonomous walking mechanism of deep coal fluidized mining equipment, which comprises a cutterhead group, a tunneling cabin, a middle cabin and a tail cabin, the sections of the cutterhead group and each cabin are rectangular, each cabin comprises a support device in contact with a top rock stratum, and the support devices provide support force in the operation process; a propelling device is arranged between every two adjacent cabins, multi-cabin collaborative stepping type autonomous walking and turning can be achieved through collaborative operation of the top supporting devices in all the cabins and the propelling devices between all the cabins, the whole device is rectangular, supporting force from the left side and the right side is not needed, and even if coal seams on the left side and the right side are mined empty areas, the device can operate normally. A spiral conveyor, a belt conveyor, a coal screening chamber and a coal storage bunker are arranged in the cabins and are used for conveying and subsequently treating mined coal. The intelligent degree of coal mining can be improved, the safety of coal mining personnel is improved, and a solution is provided for solving the mining problem of deep coal resources of 2000 m or above.

Description

technical field [0001] The invention relates to an autonomous walking mechanism, in particular to an autonomous walking mechanism for deep coal fluidized mining equipment. Background technique [0002] At present, most of my country's underground mining is located at a depth of 500m, and is extending downward at an average annual rate of 10-20m. With the increase of mining depth, the stress level of coal and rock mass increases, high ground stress, high ground temperature, and high karst water pressure appear, and the surrounding rock rheology makes it difficult to support the roadway. Coal working faces are prone to phenomena such as coal wall slabs and roof leakage; therefore, traditional underground mining is obviously limited by the mining depth and is not suitable for mining deep resources. Research shows that under the current technical conditions, the limit depth of underground mining is about 1500m, but nearly 70% of my country's solid resources are distributed at d...

On this basis, the patent CN202010156902.X proposes a structure and method for fluidized return mining suitable for deep coal resources. It is proposed that only one horizontal roadway and one fluidized resource underground mine should be laid when mining deep coal resources. The transfer station, the supply and output of the fluidized mining equipment in underground mining all pass through the transfer station, but the patent does not clarify the specific structural composition of the deep coal resource mining equipment, and how the whole set of mining equipment can independently walk underground
