Problems solved by technology

Once the injection hole phenomenon occurs, the orifice will spray high-concentration gas, which will easily cause the gas concentration in the drilling site operation environment to exceed the limit, and seriously threaten the personal safety of on-site operators

Abstract

The invention provides a drilling hole opening gas collecting device. The drilling hole opening gas collecting device comprises a collecting barrel, a wind barrel and a connecting pipe; the interior of the collecting barrel is of a hollow structure, and a first gas inlet is formed in one side end of the collecting barrel; the interior of the wind barrel is of a hollow structure, a second gas inletis formed in one side end of the wind barrel, and a first gas outlet is formed in the other side end of the wind barrel; the first gas outlet is connected with the second gas inlet in a sealing mode;and the collecting barrel communicates with one end of the connecting pipe. The drilling hole opening gas collecting device can prevent the gas concentration of a drill site from exceeding the limitand ensure the safety of operating personnel on the construction site.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a gas collection device at a bore hole. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In the environment of high temperature and high pressure, while coal is formed, gas continues to be generated due to physical and chemical effects. Gas is a colorless, odorless gas, but sometimes you can smell an apple-like aroma, which is due to the simultaneous gushing of aromatic hydrocarbon gases and gas. Gas is insoluble in water, does not support combustion and cannot maintain breathing. When the concentration reaches a certain level, it can cause people to suffocate due to lack of oxygen, and can also burn or explode. Gas exists in free state and sorption state in coal body or surrounding rock. [0003] During drilling and hydraulic punching coa...
