Description
Technical field
The present invention relates to the high-power drilling equipment applied technical field in mining area, specifically a kind of bi-directional combination type probing
Device.
Background technique
Shandong Feicheng mining area is the famous inundation mine area in the whole nation, and the extremely complex property of hydrogeologic condition currently exploits coal
It is that Taiyuan group's the following group coal need to carry out grout transformation to working face, due to by mining influence and the hydrology in inlet well work progress
The factors such as complex geologic conditions, individual hole section rocks are hard or broken, and difficulty of construction is caused to increase, or even will appear useless hole, sternly
Important place constrains production, delays stope normal continuance, and for this situation, the industry is widelyd popularize at present using high-power brill
It visits equipment and overcomes drawback existing in the prior art using measures such as overstriking, reinforcement drilling tool specifications.
Defect of the existing technology is: in existing drill bit and drilling mode, catalase section drilling, which is easy to happen, collapses
Hole accident causes the drilling accidents such as burying, reduces drilling efficiency, or even causes useless hole；Hard section of rock needs Small-diameter drill
After drilling, brill is mentioned, then changes major diameter drill bit reaming, is constructed time-consuming and laborious, in the prior art, drilling tool is divided into the core drill of different size
Head and Noncoring drill bit, wherein it is restricted when the first situation is exactly coring bit drilling by core is extracted, influences drilling efficiency,
To which construction speed is slow；Although second situation is exactly that Noncoring drill bit is high with respect to drilling efficiency, solid rock just obvious drop is met
Low rate of penetration；The third situation is exactly in crushing rock formation section drilling construction, no matter using coring bit drilling or nothing
Core drill bit drilling all there is a situation where to mention and bore difficulty, and for three cases above, we are subject to coring bit and Noncoring drill bit
Combination improves, and makes full use of its respectively advantage, avoids its deficiency, develops a kind of bi-directional combination type drilling rig, solve life
The problem of production.
Based on existing technical problem, technical characteristic and technical effect, application technical solution of the invention is proposed.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it the present invention provides a kind of bi-directional combination type drilling rig, solves
In original drilling process in drill bit and drilling mode: being easy to happen collapse hole accident in catalase section drilling, cause the holes such as burying
Interior accident reduces drilling efficiency, or even causes useless hole；After needing Small-diameter drill to creep at hard section of rock, brill is mentioned, then is changed big
Diameter drill bit reaming, time-consuming and laborious problem of constructing meet the demand of enterprise's production.
In order to achieve the above object, the technical scheme adopted by the invention is that: a kind of bi-directional combination type drilling rig includes
