Coal roadway tunneling equipment and coal roadway tunneling system with temporary uniform distribution supporting function

Abstract

The invention discloses coal roadway tunneling equipment and a coal roadway tunneling system with a temporary uniform distribution supporting function. The coal roadway tunneling equipment comprises atunneling device and a temporary supporting device, wherein the temporary supporting device comprises a spraying device and a sealed air extractor, the spraying device is arranged on a first mechanical arm, the first mechanical arm controls the spraying device to spray a spraying material onto the surface of surrounding rock of a newly tunneled roadway to form a sealing spraying layer on the surface of the surrounding rock, the sealed air extractor is arranged on a second mechanical arm, an air extraction channel is formed in the sealed air extractor, and the second mechanical arm controls the sealed air extractor to be attached to a non-spraying position reserved on the surface of the surrounding rock by the spraying device, so that the exterior of the sealed air extractor and the sealing spraying layer are sealed mutually, the air extraction channel communicates with surrounding rock cracks, and the air extraction channel is used for extracting air in the surrounding rock cracks toenable the surrounding rock to be in a negative-pressure state. According to the equipment, the air in the surrounding rock can be extracted through the temporary supporting device, so that the surrounding rock is in a negative-pressure state to generate a temporary supporting effect on the newly-formed roadway.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a coal roadway driving equipment and system with the function of temporary evenly distributed support. Background technique [0002] At present, due to the generally low strength of coal-measure strata and the development of fissures, support must be carried out in time after the excavation section is formed to ensure the safe mining of coal. Traditional support methods are metal probe beams, single hydraulic props, etc., which require manual handling for support. The construction speed is slow, the support strength is insufficient, the support quality is poor, and the labor intensity is high. In order to solve this problem, related technologies In the roadheader, the airborne roof or the self-moving shed bracket is used for support, but the operation is cumbersome, time-consuming, the support area is small and easy to damage, and it is difficult to meet the needs of rap...
