Description

Supporting device and method for fully mechanized mining face transportation channel and its application

technical field

The invention relates to a support device and a method, in particular to a support device and method for a fully mechanized mining working face transporting a chute and an application thereof.

Background technique

The working face chute is a mining roadway excavated for coal seam recovery. There are generally two working face chutes, namely, the transport chute and the return air chute. The transport chute is equipped with a belt conveyor, which is responsible for transporting the coal out of the working face. At the same time, the wind is transported along the trough, and the return air is returned along the trough. Therefore, the support device and method used for the transportation along the trough of the fully mechanized mining face and its application are an important mine device. In the support device and method on the transport channel of the mining face and its application,

When the roof of many coal mine roadways is relatively broken, the stacked advanced support is often used, because the stacked support adopts a large cycle, that is, the tail stock is changed to the first frame to advance, and the roof is always supported, so there will be no roof sinking, Phenomena such as deformation, the existing technology such as the stack-type advanced support, without a four-bar linkage mechanism, the stability and anti-eccentric load capacity cannot be compared with the step-type advanced support. The stack-type advanced support is generally dragged by a winch. The frame is lowered and moved to the front end, which can avoid repeated support and damage to the roof, but the disadvantage is that the roadway required by this transportation method is relatively wide, and there are reloaders and belt conveyors along the trough for transportation on the working face, so the space is extremely limited. If this kind of support is used, the amount of excavation and roof pressure along the coal mine transportation will increase, which will affect the recovery efficiency of the coal mine working face and cause great safety hazards.

The step-by-step self-moving advanced support has a stable four-bar linkage mechanism, which has large working resistance and a large support area. However, its moving method is step-by-step self-movement, and the distance between each step is about 700mm. It supports the roof repeatedly, and the damage of the roof is serious. The step forward support has a four-bar linkage mechanism, which has a strong bearing capacity, but is bulky. The forward movement mainly depends on the push jack on the base. The step distance of the push jack is generally 700mm. If it is arranged in a long distance, every 700mm, the whole frame must be lowered and then moved forward. The roadway roof is repeatedly raised, lowered and moved by the support crushed during the process, which is not conducive to the maintenance and management of the roof,

Especially when the roof is relatively broken, and the transport chute is close to the goaf of the previous working face, the maintenance workload of the roof is very huge. In this case, the use of the stepping forward support will aggravate the brokenness of the roof, which comes from the work Face mining and the pressure of the goaf will make the deformation of the transport channel more and more serious, which will lead to difficult problems such as insufficient ventilation section, insufficient space for coal transportation, and inability of the transfer machine and support to move forward.

Based on the applicant's technical disclosure document and the existing technical problems, technical features and technical effects in the background technology, the technical proposal of the present invention is made.
