An integrated drilling and drilling machine and method based on high-pressure foam medium

Abstract

The invention discloses an integrated rock-drilling machine based on a high-pressure foam medium, comprising: a mechanical device of the integrated drilling-expanding rock-drilling machine, a high-pressure foam generating and conveying system, and a hole sealing device. The integrated drilling and drilling machine includes a power unit, an impact piston, a motor, a transmission gear set, an impact rotary drill bit, a drill pipe, a drilling sealing device, a high-pressure foam delivery chamber, and a high-pressure foam generation and delivery system. The high-pressure foam generation and delivery system includes a liquid pump, a gas pump, a liquid-gas mixer and a supercharger, which can adjust the liquid-gas mixing ratio and delivery pressure according to different rock hardness conditions; The efficiency of hole, sealing and cracking operation is low, the process is complicated, etc., to avoid the error of sealing and cracking caused by the drilling and sealing operation of the working face of the drilling machine, and to realize the continuous operation of the integrated drilling and drilling machine , effectively improving the operating efficiency of the drilling machine.

Description

technical field [0001] The invention relates to an integrated rock drilling machine, in particular to an integrated rock drilling machine and method based on a high-pressure foam medium, belonging to the technical field of rock drilling machinery. Background technique [0002] The national "Thirteenth Five-Year Plan" proposes to increase the proportion of non-fossil energy, promote the clean and efficient utilization of fossil energy such as coal, the safe development of deep coal resources, the green development of western coal resources, the clean and efficient utilization of coal and other basic theoretical research and key technology research needs. Breakthroughs have been made; the level of safety technology and equipment has been greatly improved, and progress has been made in the detection of hidden disaster-causing factors in coal mines. In the process of coal mining, the imbalance of mining ratio has always been the main factor affecting the high yield and high effi...

Problems solved by technology

Comprehensive tunneling method is an advanced rock tunneling technology, but in the process of hard rock tunneling, the unit specific energy consumption is too large, the loss of the drill bit is serious, the reliability and adaptability of the machine are poor, and it is not suitable for the development of hard rock tunnels

At present, the drilling and blasting method is mainly used in the excavation of hard rock roadways, and explosives are used to realize instant blasting. The processes of rock breaking, gangue removal and support require their own special equipment. Due to the limitation of working space and working surface, it is difficult to realize simultaneous and continuous permanent excavation, and the surrounding rock is severely damaged and the degree of mechanization is low, which seriously affects the purpose of safe and efficient production. At the same time, the labor intensity of the workers is high, and the dust and equipment construction noise affect the health of the workers.
