A connection pipeline well and construction method for inclined ore body

Abstract

The invention relates to a contact pipeline well used on an inclined ore and a construction method of the contact pipeline well. The contact pipeline well comprises an upper end driftway, a lower end driftway, a vertical pore channel and a lower end pore channel, one end of the vertical pore channel communicates with the upper end driftway, the other end of the vertical pore channel communicates with one end of the lower end pore channel, and the other end of the lower end pore channel communicates with a lower end driftway; and the construction method comprises the steps that a raise-boring machine is utilized to drill the vertical pore channel and a full-hydraulic trackless drill jambo is utilized to drill horizontal pore channels. By adopting the technical scheme of the contact pipeline well used on the inclined ore and the construction method of contact pipeline well, the pipeline well is not parallel to the side face of a slope of the ore body while being composed of the vertical pore channel and the multiple horizontal pore channels, the work such as explosive filling and blasting do not need to be conducted on the ore body in the construction technology, so that the construction technology is simplified, the damage to internal stress balance of the ore body and pollution to the environment are avoided, and the construction working efficiency of the pipeline well is improved.

Description

technical field [0001] The invention belongs to the technical field of mine construction, and in particular relates to a connecting pipeline well on an inclined ore body and a construction method. Background technique [0002] In mining and construction operations, mine pipeline wells are generally roadways used to install mechanical equipment such as pressurized air pipes, drainage pipes, power supply cables, and communication lines, or mining tools. The cross-sections of pipeline wells are generally small. Most of them are about 3 meters × 3.2 meters. In the prior art, common rock drilling methods are mostly used in rock formation mine construction projects. When using this method, relevant workers need to enter the narrow and small mines hundreds of meters deep. Excavation work is carried out in the excavation working face. The excavation work requires the use of drilling rigs and other tools. It requires complex construction processes such as drilling and blasting holes,...

[0002] In mining and construction operations, mine pipeline wells are generally roadways used to install mechanical equipment such as pressurized air pipes, drainage pipes, power supply cables, and communication lines, or mining tools. The cross-sections of pipeline wells are generally small. Most of them are about 3 meters × 3.2 meters. In the prior art, common rock drilling methods are mostly used in rock formation mine construction projects. When using this method, relevant workers need to enter the narrow and small mines hundreds of meters deep. Excavation work is carried out in the excavation working face. The excavation work requires the use of drilling rigs and other tools. It requires complex construction processes such as drilling and blasting holes, loading explosives, and blasting the working face. After excavation, the rock must be lifted to the ground by tools such as buckets. , laying pipelines after draining and supporting the working face, this method not only has a low level of mechanization, but also requires a large labor force, the working environment is difficult, the safety conditions are poor, and the efficiency is relatively low. Severe stress changes greatly, support is difficult, and endangers the personal safety of operators, especially for the construction of pipeline shafts in mines with inclined slopes, the construction is usually carried out along the longitudinal direction of the ore body parallel to the inclined slope, and only the use of Electric or pneumatic hand-held rock drills and drilling machines need to use explosives to blast and blast, which seriously endangers the personal safety of operators. Pollution is very big; For example, publication number is the patent literature of " CN103850684A ", discloses a kind of shaft boring machine to expand the drilling technique of raising well drilling machine guide well, comprises the following steps: (a) utilizes raising drilling machine to drill into guiding well; (b) Drilling with a shaft boring machine to make the guide shaft brush larger to the required diameter of the shaft; (c) hanging nets and spraying concrete on the shaft wall to form a temporary support shaft wall; (d) using a shaft boring machine After brushing and digging into the lower roadway, the shaft boring machine components are gradually dismantled from top to bottom; using the technical scheme of the invention, a vertical shaft with a larger diameter is drilled using a raise drilling machine and a shaft boring machine, but the diameter of the pipeline shaft is smaller. Small, the technical solution of the invention cannot be applied, and when the ore body has a slope side, the shaft boring machine cannot be applied, which affects the scope of application of the invention
