Description
Technical field
The present invention relates to a kind of drilling equipment, specifically one be applicable to underground coal mine roadway floor carries out anchor pole of holing
Supporting from the steady boring device of movable base plate anchor pole, belong to down-hole support equipment technical field.
Background technology
Due to the self-characteristic of different depth rock mass and the difference of residing ambient stress around tunnel, transported by geologic rhythm
The factor impacts such as dynamic, ground water pressure, country rock easily produces Incoordinate deformation, exploits especially for underground coal mine, top, tunnel, the end
Plate and two helps country rock to be deformed and move in tunnel, and the phenomenon that wherein roadway floor or gob floor upwards swell is i.e.
Referred to as pucking, pucking is a kind of dynamic phenomenon often occurred in roadway, it and the character of country rock, mining influence, mining depth
And geological structure etc. is directly related, some Floor Heave in Roadway amount of domestic mine even account for top, tunnel, the base plate amount of shifting near 70% with
On, bigger particular for mining depth, have that stress is high, temperature is high, subsoil water hydraulic pressure is high, strength of turbulence is high, danger of burst
The deep-seated setting of feature, high stress and soft rock mine roadway and the chambers such as height, creep is obvious, deformation is big, pucking makes roadway deformation, section become
Little, drastically influence the links such as mine ventilation, transport and personnel's walking, restriction mine safety and high-yield and high-efficiency and produce.
Underground coal mine prevents the generation of pucking phenomenon from not only wanting reinforcement roadway support, reinforced design method, and will be according to specifically
Wall rock geology condition take measures pucking amount is reduced to allowed band, generally use method for strengthening, destressing method, combination method and add
Gu the methods such as tunnel side, angle reduce pucking phenomenon, wherein method for strengthening is to be enclosed base plate by raising floor rocks intensity or raising
The supporting power of rock reaches the purpose of floor lift control, is a kind of the most frequently used pucking control method.
Improve the intensity of floor rocks, mainly have floor grouting, floor bolting etc., base plate is being used suspension roof support
Needing during operation first to hole base plate, traditional method need to be with pin or reversely air leg support above drilling rod in boring procedure
On back, to provide reverse holding power, but due in order to ensure that roadway floor does not destroys before installing anchor pole, it is necessary to
Installing anchor pole in driving face certain distance, the size of this distance is relevant with the character of floor rock, typically should be little
In 10 meters, the most unaffected in order to ensure tunnelling speed, the speed of usual rockbolt installation wants fast, and this traditional brill
Hole method operation not only complicated, manpower and materials consume big, and hole and install the speed of anchor pole compared with slow, efficiency is low, inadaptable
Requirement in Quick Road-Made.
