Thin coal seam N00 construction method mining, cutting and anchoring system

Abstract

The thin coal seam N00 construction method mining, cutting and anchoring system comprises a walking mechanism and a cutting mechanism, a shovel plate mechanism, a supporting mechanism, an anchor rod mechanism and a joint cutting mechanism which are arranged on the walking mechanism, and is characterized in that the walking mechanism is composed of a lower base and two walking tracks fixed to the two sides of the lower base; an upper base capable of moving front and back in the length direction of the walking crawler belt is arranged on the lower base, guide columns, first telescopic oil cylinders and positioning blocks are arranged on the two sides of the upper base, the positioning blocks are fixed to the lower base, the guide columns can be inserted into the positioning blocks in a front-back moving mode, and the cutting mechanism and the shovel plate mechanism are fixed to the front end of the upper base. According to the thin coal seam N00 construction method mining, cutting and anchoring system, the upper base is driven by the first telescopic oil cylinder to move forwards on the lower base, the cutting length of the cutting mechanism to a coal seam roadway can be extended under the condition that the whole machine is not moved, and the phenomenon that dead corners which cannot be cut exist on the two sides of the roadway when a cutting head can only rotate is avoided.

Description

technical field [0001] The invention relates to a cutting and cutting anchor system in the process of coal mining, more particularly, to a cutting and cutting anchor system of a thin coal seam N00 construction method. Background technique [0002] Coal is the largest energy source in my country, and the scientific and rational mining of coal mines plays a decisive role in alleviating resource shortages and protecting the ecological environment of mining areas. Coal mining methods include 121 construction method, 111 construction method, 110 construction method and the recently proposed N00 construction method. In the 121 construction method system, mining a working face needs to go through the process of excavating roadways, coal mining, destroying roadways, and leaving coal pillars, which will be accompanied by many processes. question. The 111 construction method means one working face, one roadway is excavated in advance, and one backfill column is left, which will cause...

Problems solved by technology

[0003] However, the literature mentioned in the N00 construction method uses a lot of supporting equipment, and does not use the rapid roadway formation of the roadway. In the N00 construction method, it uses the N00 slotting drilling machine, the N00 constant resistance anchor drilling machine, the N00 multifunctional drilling machine support and the N00 cutting machine. The complete set of core equipment for the roof protection bracket has a total of four equipments. The four equipments used in it work independently and need four equipments to work together, which is not conducive to the rapid construction of the roadway. Moreover, multiple equipments work together, requiring a large number of personnel, and four equipments are required. The operator of each equipment is skilled in cooperation
