Description

Supporting device and method for fully mechanized coal mining face transportation crossheading and application of supporting device and method
Technical Field
The invention relates to a supporting device and a supporting method, in particular to a supporting device and a supporting method for a fully mechanized coal mining face transportation crossheading and application thereof.
Background
The working face crossheading is a mining roadway excavated for mining a coal seam, the working face crossheading is generally provided with two conveying crossheading and a return air crossheading, the conveying crossheading is provided with a belt conveyor which is responsible for conveying coal out of the working face, conveying inlet air of the crossheading and returning air of the return air crossheading, so that the supporting device and the method for the fully mechanized working face conveying crossheading and the application thereof are important mine devices, and in the existing supporting device and the method for the fully mechanized working face conveying crossheading and the application thereof,
under the condition that a plurality of coal mine tunnel roofs are broken, a stack type advance support is adopted mostly, the stack type advance support is pushed in a large circulation mode that a tail frame is changed into a first frame, and the top plate is always in a supporting state, so the phenomena of sinking, deformation and the like of the top plate cannot occur. If the bracket is adopted, the excavation amount of the coal mine transportation gate way and the pressure of the top plate are increased, the recovery efficiency of the coal mine working face is influenced, and greater potential safety hazards exist,
the walking self-moving type forepoling has a stable four-bar mechanism, the working resistance is large, the supporting area is large, but the moving mode of the advancing self-moving type forepoling is that the walking self-moving type forepoling moves, the advancing step distance is about 700mm, the roof is repeatedly supported, the roof is seriously damaged, and the walking type forepoling has the four-bar mechanism, the bearing capacity is strong, but the size is large. The forward movement mainly depends on a pushing jack on the base, the step pitch of the pushing jack is generally 700mm, if the pushing jack is arranged in a long distance, the whole support is lowered every 700mm, then the support is moved forward, the roadway roof is crushed in the process of repeatedly lifting, lowering and moving the support, the maintenance and management of the roof are not facilitated,
particularly, when the top plate is broken and the transportation crossheading is close to the goaf of the previous working face, the maintenance workload of the top plate is very huge, in this case, the broken degree of the top plate is aggravated by using the walking type forepoling, the transportation crossheading is more and more seriously deformed by the pressure from the working face mining and the goaf, and further, the difficult problems of insufficient ventilation section, insufficient coal conveying space, incapability of moving a transfer conveyor and a bracket and the like are caused,
the technical scheme of the invention is made based on the technical problems, technical features and technical effects in the technical background of the applicant.
