Generally, the deformation of the high-stress weak surrounding rock roadway can cause the phenomenon that the bottom plate swells. The influence of the bottom drum on the roadway is great, the section of the roadway is reduced, the foundation and the rail of the bottom plate are damaged, and the requirements of transportation, ventilation and pedestrians in the roadway are greatly influenced. For the treatment of the bottom heave, measures such as bolting, anchor cable and grouting can be generally carried out on the bottom plate. However, the implementation of the measures needs to drill the bottom plate rock mass, and the quality of the drilled hole directly influences the installation quality and grouting effect of the anchor rod and the anchor cable. At present, the construction of drilling the bottom plate mostly adopts the wind anchor head to connect the twist drill rod or adopts the down-the-hole hammer, but when adopting the wind anchor head to connect the twist drill rod and drilling, along with the deepening of the drilling depth, the rock dust or the coal dust in the drilling will increase thereupon, the existence of bottom plate crack water in addition to serious sticking phenomenon appears, the drilling depth can only be hit about 2m, can not satisfy bottom plate stock, anchor rope installation requirement. When the down-the-hole hammer is adopted for construction, the minimum drilling diameter of the down-the-hole hammer is 76mm, so that the high-pressure grouting requirement of an anchor rod, an anchor cable and a bottom plate cannot be met. At present, the construction of drilling the bottom plate is an industrial problem, so the reverse circulation bottom plate anchor cable drilling machine can effectively solve the problem of drill sticking. The present invention has been made to enable drilling of a base plate to be smoothly performed.
