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
The present invention relates to the coal mining field, particularly the method for a kind of coal mine roadway speedy drivage continuous supporting operation.
Background technology
Driving is two key links of roadway construction with supporting, safety, fast, economic, tunnelling efficiently and supporting be to guarantee that colliery realizes highly efficient and productive prerequisite, is the decisive factor that realizes the mine maximum economic benefit.The coal mine roadway construction technology all adopts " first dig afterwards and prop up " at present, driving carries out with supporting is staggered, and support material and technique also adopt Bolt-rope Supports more, first carry out bolt support, then implement the anchor cable reinforcing, support time accounts for more than 70% of roadway construction total time.Improve driving speed (combining pick or big gun pick), simplify support process, increase support material intensity and reduce support density and improved to a certain extent speed of application, but can't fundamentally improve greatly the speed of roadway construction, reduce construction cost.Therefore, device and the technique of developing a kind of coal mine roadway speedy drivage and continuous supporting operation are to solve tunnel safety, economy, quick, an efficient crucial difficult problem of constructing, therefore driving is imperative with the improvement and bring new ideas of two links of supporting.
