Problems solved by technology

This is mainly due to the loose body structure of the gangue, which is a porous medium, which is prone to drill sticking, hole collapse, and reddening and softening of the drill bit during drilling construction, making grouting drilling more difficult.
Therefore, the grouting drilling method needs to be improved urgently, but at present, there is no drilling method that can adapt to the loose rock mass structure and effectively improve the porosity rate and drilling efficiency.

Abstract

The invention provides a loose rock body drilling device. The loose rock body drilling device comprises a drilling machine, a drilling rod, a positioning vertical platform and a supporting truss; the drilling machine and the drilling rod are fixed on the positioning vertical platform and the drilling rod is vertical to the ground; the positioning vertical platform is fixed on the supporting truss; guide rails are mounted on the positioning vertical platform; under a working state of the drilling machine, the drilling machine does reciprocating motion on the guide rails; the supporting truss is of a herringbone shape and comprises a transverse beam; rolling wheels are mounted at the bottom of the supporting truss and the transverse beam is used for fixing the positioning vertical platform; and the rolling wheels are used for moving the supporting truss together with the drilling machine to a pre-set position when the drilling machine needs to work at other places. The loose rock body drilling device is simple in structure and easy to operate; and the problems that the drilling efficiency is low, the hole forming rate is low and the safety is poor when drilling and grouting work is carried out in a loose rock body can be effectively solved.

Description

technical field [0001] The invention relates to a drilling device and method, in particular to a drilling device and method suitable for loose rock mass. Background technique [0002] The high and steep gangue hills formed by the open-air accumulation of coal gangue not only occupy a large amount of land resources, pollute the surface and underground water sources, but also release a large amount of SO 2 , CO, H 2 Toxic and harmful gases such as S and benzo(a) castor cause air pollution and damage to the ecological environment, and may cause more destructive disasters such as water gas explosions, causing serious property losses and casualties. It is of great safety and economic significance to control gangue dumps and prevent spontaneous combustion of gangue dumps. [0003] At present, one of the more commonly used methods to prevent spontaneous combustion of gangue dumps is the grouting fire extinguishing method. The grouting fire extinguishing method drills and injects...
