Drill hole spray safety protection system

Abstract

The invention discloses a safety and protection system for use in drilling operations. The system is characterized by comprising an orifice multi-way device provided with a drill stem passage, an expandable connecting pipe made of high-strength filament fiber cloth with spiral flexible steel wire sewn in an interlayer, a pair of soft coal storage and slag discharge devices symmetrically connected to outlet openings at two sides of a three-way slag discharge device, a coal gas purifier provided with a dust bin which has a side wall communicated with a drainage passage of the orifice multi-way device through an intake pipe and the other side wall is communicated with the drainage passage through an exhaust pipe. While ensuring the normal advance and retrace of the drill stem, the system can block the hole to prevent coal and gas from jetting right forward and smoothly lead coal powder and gas jetted from the hole to a preset device, thereby eliminating safety hazards caused by strong jet from a drill hole or by a protruding drill hole.

AI Technical Summary

Benefits of technology

This patented technology allows for faster removal of airborne particles during drillings without increasing their concentration levels inside the tunnel being worked on by injectors. By separating these materials before they enter the tunnel, this helps avoid damage caused by increased gases within the tunnel's environment. Additionally, there is provided a mechanism called triple valve devices used to control the direction of fluid movement between different parts of the apparatus. These technical features help improve efficiency while reducing problems such as blockages due to deposits formed around openings in pipes.

Problems solved by technology

This patents discusses two technical problem addressed by current methods for controlling drained gases: firstly due to blockages caused by injected water that can be harmful even if they don't affect important areas such as roads; secondly, with regards to storing excessive amounts of dust and debris around these drainage sites without being able to effectively manage them properly.
