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 stoping roadway excavated for stoping a coal bed, and generally comprises two working face crossheadings, namely a transport crossheading and a return air crossheading, wherein the transport crossheading is provided with a belt conveyor which is used for transporting coal out of the working face, transporting inlet air into the crossheading and returning air into the return air crossheading,
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 and the pressure of the top plate are increased, the mining 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, has large working resistance and large supporting area, but the moving mode of the advancing self-moving type forepoling is walking self-moving, the advancing step distance is about 700mm, the roof is repeatedly supported, the damage to the roof is serious, and the walking type forepoling has the four-bar mechanism, has strong bearing capacity and large volume. 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, under the condition, the walking type forepoling is used, the breaking degree of the top plate is aggravated, the transportation crossheading is deformed more and more seriously due to the pressure from the working face mining and the goaf, and further troublesome problems of insufficient ventilation section, insufficient coal conveying space, incapability of moving a transfer conveyor and a support 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.
