Supporting method for superhigh sections of two ends of fully-mechanized mining face

Abstract

The invention relates to a coal mine supporting technology and provides a supporting method for superhigh sections of two ends of a fully-mechanized mining face, aiming at solving the supporting problem of the superhigh sections of local district roadways of intake and return airways. When driving to the superhigh sections, workers lower each hydraulic support to a lowest position, mount a hydraulic telescopic supporting device to the top of the hydraulic support and connect the hydraulic telescopic supporting device to a control device nearby a supporting frame handle through a hydraulic pipeline, and a hydraulic source is a pump station using a matched working face, so that safe and rapid operation is achieved, a fully-mechanized method for passing the superhigh sections flexibly, safely, efficiently, conveniently and rapidly is achieved, operation is facilitated, cost is saved, a high-strength high-altitude operation method that personnel nog above 2.5-meter shed beams during shed erecting construction is avoided, and nogging and shed erecting timbers and shed erecting cost are decreased. A power source and electrical control equipment do not need to be added; on the premise of not upgrading into ultrahigh supports, tasks which cannot be completed by original supports can be completed by additional mounting of a set of equipment.

Description

technical field [0001] The invention relates to a coal mine support technology, in particular to a support method for both ends of a fully mechanized mining face over a superelevation section. Background technique [0002] Such as figure 1 As shown, during the mining process of the coal mining face, the superelevation of the roadway in some sections of the inlet and return air lanes is sometimes as long as 40 meters, and the maximum height of the roadway reaches about 4.0 meters. Roof support with wooden stacks hooking the roof is labor-intensive, and many supporting materials are used and cannot be reused after the support is completed. Moreover, there is high-altitude operation of wooden stacks on the shed beams, which makes safety management difficult. The performance is: high labor intensity, high cost, and difficult safety management. Contents of the invention [0003] In order to solve the support problem of the ultra-elevation section of the roadway in the local s...
