Intelligent self-adaption coal mining machine for thin coal seam and coal mining cutting method

Abstract

The invention discloses an intelligent self-adaption coal mining machine for a thin coal seam and a coal mining cutting method. The coal mining machine comprises walking parts, a machine body part, cutting parts, a hydraulic part, an electronic control part, an intelligent detection part and a fault warning part. The walking parts are arranged at both ends of the machine body part in the length direction of a scraper conveyor. The cutting parts include a main cutting part and two auxiliary cutting parts, the main cutting part is located in the middle of the machine body part, and the two auxiliary cutting parts are located at both ends of the machine body part. The hydraulic part and the electric control part are installed in the inner side of the machine body. The intelligent detection part is arranged on the main cutting part. The fault warning part is arranged on the machine body part. The coal mining cutting method comprises the steps that information is collected by the intelligent detection part, and processed and analyzed by the electronic control part, inclined cutting grooving is carried out through the auxiliary cutting part on one side for unloading, the coal walls on the peripheries of unloading grooves are cut by the main cutting part, the remaining coal walls are cut or profile modification of bottom edges is carried out by the auxiliary cutting part on the otherside, intelligent obstacle-navigation during the cutting process is carried out until a cutting surface is completed, the direction is turned and cutting is carried out continuously.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to an intelligent thin coal seam self-adaptive coal shearer and a coal mining cutting method. Background technique [0002] Thin coal seam refers to the coal seam whose thickness is less than 1.3m. Thin coal seam accounts for a large proportion of my country's coal resource reserves. With the improvement of the manufacturing level of coal mining equipment, and on the basis of high power and high reliability, in order to realize The high-yield and high-efficiency mining of thin coal seams should be based on the actual occurrence of coal seams, and the appropriate coal mining machinery and coal mining methods should be selected according to local conditions. [0003] At present, there are mainly two types of thin coal seam mining methods, which are divided into "explosive mining" and "mechanical mining". Among them, the "explosive mining" method has the disadvantages of...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the present invention provides an intelligent thin coal seam self-adaptive coal shearer and a coal shearer cutting method, in order to avoid excessive vibration of the coal shearer body and encounter uneven roadways when mining coal When the roof and floor are on the roof, the shearer can automatically avoid and overcome obstacles, so as to overcome the difficult problem of cutting due to the stress of the surrounding rock of the thin coal seam, realize the unloading of the stress of the thin coal seam, and then reduce the size of the shearer body. The working load of internal parts and picks not only improves the service life of the cutting drum of the shearer, but also further improves the coal mining efficiency of thin coal seams
