Raise drilling equipment and technology for gas cooling and slag discharge in water-deficient environment

Abstract

The invention discloses a raising drilling equipment and technology for gas cooling and slag discharge in a water-deficient environment. The raising drilling equipment includes a raising drilling rig hydraulic control system, an air-cooled cooler and an air compressor. The raising drilling rig The oil return main pipe of the hydraulic control system is in fluid communication with the high-temperature hydraulic oil inlet of the air-cooled cooler, and the low-temperature hydraulic oil outlet of the air-cooled cooler is in fluid communication with the oil return port of the hydraulic oil tank; the air compressor The cold air discharged from the air outlet of the machine enters the bottom of the drill bit; high-pressure compressed air is used to wash and lift the broken rock slag produced by the bottom hole drilling tool when drilling the pilot hole of the raised shaft, and high-pressure compressed air is used to carry out the drilling when drilling the raised hole. Cooling of reaming drill hobs. The invention can solve the problem of heat dissipation without clean water source, and can realize the effective cooling of the raising drilling hydraulic oil and the hob of the reaming bit and the effective collection and discharge of pilot hole drilling slag.

Description

technical field [0001] The invention relates to the technical field of raising well drilling. Specifically, it is a raising drilling equipment and process for gas cooling and slag discharge in a water-deficient environment. Background technique [0002] Raise drilling rigs have played an important role in hydropower, mining, transportation, construction and other fields since they were widely used in underground engineering construction in the 1980s. With the rapid development of my country's national economy, the scale of underground engineering construction is increasing day by day, especially the construction of traffic tunnels and metallurgical mines is very large, and it is necessary to drill ventilation shafts in the mountains. [0003] The auxiliary system of the raise drilling rig is composed of cooling, slag discharge, circulation, measurement, water supply and power supply. At present, the main links that require water sources in the raising well construction pro...

Problems solved by technology

[0004] When roads, railway tunnels or metallurgical mines are located in areas with harsh natural climates such as Gobi, high altitude, high cold, severe water shortage and drought, or poor engineering geological conditions such as unstable surrounding rocks, broken and cracked zones, the construction water is faced Great difficulties, such as hydraulic oil, reaming drill bit and hob cannot be cooled due to insufficient water supply, problems such as poor lifting and discharge of broken rock slag, it is difficult to ensure the normal implementation of the process and the normal progress of the project
