Method for quickly tunneling mine roadway and consecutively timbering mine roadway

Abstract

The invention relates to a method for quickly tunneling a mine roadway and consecutively timbering the mine roadway. The method can effectively solve the problem that construction speed can not be fundamentally improved due to the fact that tunneling a roadway and timbering the mine roadway are conducted in a staggered mode. According to the technical scheme, the method comprises the following steps: (1) comprehensively tunneling the roadway or digging a roadway through a cannon, digging out waste rocks and drilling an anchor cable; (2) drilling a top anchoring rod; (3) drilling an auxiliary anchoring rod; (4) moving the waste rocks out. When the roadway is tunneled in a comprehensive mode, the step (1) and the step (3) can be conducted at the same time. When the roadway is tunneled through a cannon, digging the waste rocks out, drilling new cannon holes, the step (1), the step (2) and the step (3) can be conducted at the same time. The operation method is simple, improves tunneling speed due to the fact that tunneling and timbering are conducted at the same time, simplifies timbering technology, shortens initial top plate timbering time, improves the stability of top plates, reduces construction strength, effectively improves roadway construction speed, saves cost, and is good in utilization time and innovative in tunneling and timbering method.

Description

technical field [0001] The invention relates to the field of coal mine mining, in particular to a method for rapid excavation and continuous support operation of a coal mine roadway. Background technique [0002] Driving and supporting are two key links in roadway construction. Safe, fast, economical and efficient roadway driving and supporting are the prerequisites for ensuring high production and high efficiency in coal mines, and the decisive factor for realizing the maximum economic benefits of mines. At present, the construction technology of coal mine roadway adopts "excavation first and support later", and the excavation and support are carried out alternately, and the support materials and techniques are mostly combined support with bolts and cables. Strong reinforcement, the support time accounts for more than 70% of the total roadway construction time. Increasing the speed of excavation (mechanized excavation or gun excavation), simplifying the support process,...
