Abstract

The invention provides a rapid tunneling system and a rapid tunneling method. The rapid tunneling system comprises a tunneling device, a temporary supporting device, a support conveying device and a plurality of supporting devices; the tunneling device comprises an advancing assembly and a cutting assembly; the temporary supporting device comprises a plurality of supports, and each support has a supporting state and a retracting state; the support conveying device is arranged on a tunneling device, and the support conveying device comprises a supporting assembly used for jacking a support, after the cutting assembly conducting cutting for a preset time, the supporting assembly jacks at least one support, the support is switched from a supporting state to a retracting state, the support conveying device drives the support to move to a preset position, and the support is switched from the retracting state to the supporting state to support a roadway; and the supporting devices are located at the downstream position of the tunneling device, and when the support conveying device drives the support to move to a preset position, the supporting devices conduct anchor rod and / or anchor cable supporting on the roadway. The problems that in the prior art, the roadway tunneling efficiency of coal mining is low, and the production schedule is affected are solved.

Description

Technical field [0001] The invention relates to the technical field of mining equipment, and in particular to a rapid tunneling system and a rapid tunneling method. Background technique [0002] At present, there are two main methods of domestic coal mining: one is machine excavation (such as a roadheader); the other still uses the old-fashioned way of drilling and blasting. During the tunneling of the two methods, most support methods are bolt support. [0003] In the prior art, the working process of the roadheader excavation is as follows: first, the roadheader device cuts, and the roadheader stops after one cycle of cutting, and a manual hand-held monolithic roof bolter or a windlass machine-mounted roof bolter is used Carrying out bolt and cable support, first digging and then supporting. It usually takes 7 to 15 minutes for the tunneling device to cut a cycle. It takes more than half an hour to complete the anchor cable and bolt support operations, which seriously affects th...
