Abstract
The invention discloses a method for drilling a hole with plastic clay for protecting the wall of the hole, which relates to a drilling method. The invention aims to provide the method for drilling the hole with the plastic clay for protecting the wall of the hole, which can effectively prevent drill hole wall from collapsing and jamming of a drilling tool, and can improve the hole quality and charging conditions as well as the blasting effect. The aim of the invention is achieved through the following technical proposal: the method for drilling the hole with the plastic clay for protecting the wall of the hole comprises the following steps: (1) adding water to clay and blending the mixture into a plastic state; (2) in the process of drilling a bore hole, when a rock land lot is crushed, forming the hole preliminarily first, then pulling out the drilling tool, putting the plastic clay into the bore hole, putting the drilling tool into the hole again, and moving a drill bit up and down while rotating so that the drill bit drags and extrudes the plastic clay; and (3) blocking the orifice of the bore hole after the hole is formed, and waiting for charging. The method is mainly applicable for drilling holes in blasting engineering.
Description
Technical field
The present invention relates to a kind of boring method, particularly relate to a kind of method for drilling hole with plastic clay for protecting wall of hole.
Background technology
Along with the continuous development of blasting technique, medium-length hole blasting has been widely used in the rock blasting construction at present, but because the limitation of rig, under fragmented rock condition comparatively, blasthole drilling hole difficult quality guarantee is prone to hole wall collapse, bit freezing in boring procedure, and the pore-forming hole wall is coarse, when using emulsification strip powder stick, powder charge difficulty etc., therefore, under the fractured rock condition, how to improve drilling quality and efficient, still do not have good method so far.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can prevent effectively that under the fractured rock condition borehole wall from caving in and bit freezing, and can improve hole quality, improve charging condition, improve the method for drilling hole with plastic clay for protecting wall of hole of demolition effect.
The objective of the invention is to realize by following technical proposal: method for drilling hole with plastic clay for protecting wall of hole may further comprise the steps:
(1), clay is added water and be modulated into plastic state;
(2), in the process of blasthole drilling hole, when running into the fractured rock location, earlier preliminary pore-forming proposes drilling tool then, puts into plastic clay in the big gun hole, again drilling tool is put into boring, and drill bit is moved up and down while rotating, and allows drill bit drag and pushes plastic clay;
(3), aperture, big gun hole is stopped up the wait powder charge behind the pore-forming.
From method feature of the present invention as can be seen, the invention has the advantages that: clay is under the drive and extruding of drill bit, and part enters the fractured rock slit, and part is coated on the hole wall, has stablized loosening stone, has guaranteed the smooth of hole wall; Utilize the hole with plastic clay for protecting wall technology, solved the problem of borehole collapse, bit freezing under the fractured rock condition, improved drilling efficiency, saved the boring cost, guaranteed hole quality, help powder charge and improve whole demolition effect.
The specific embodiment
The present invention is described further below by embodiment:
Preferred embodiment
Method for drilling hole with plastic clay for protecting wall of hole may further comprise the steps:
(1), clay is added water and be modulated into plastic state;
(2), in the process of blasthole drilling hole, when running into the fractured rock location, earlier preliminary pore-forming proposes drilling tool then, puts into plastic clay in the big gun hole, again drilling tool is put into boring, and drill bit is moved up and down while rotating, and allows drill bit drag and pushes plastic clay;
(3), aperture, big gun hole is stopped up the wait powder charge behind the pore-forming.
Claims (1)
1, method for drilling hole with plastic clay for protecting wall of hole is characterized in that may further comprise the steps:
(1), clay is added water and be modulated into plastic state;
(2), in the process of blasthole drilling hole, when running into the fractured rock location, earlier preliminary pore-forming proposes drilling tool then, puts into plastic clay in the big gun hole, again drilling tool is put into boring, and drill bit is moved up and down while rotating, and allows drill bit drag and pushes plastic clay;
(3), aperture, big gun hole is stopped up the wait powder charge behind the pore-forming.
