Description
TECHNICAL FIELD
[0001] The utility model relates to the roadway support field, concretely relates to a hole cleaning device for drilling. BACKGROUND
[0002] Drilling operation is a basic and key construction link in roadway support engineering, and its quality is directly related to the stability, safety of roadway and the smooth progress of subsequent mining work. The main purpose of drilling operation is to provide space for the installation of support components such as anchor rod and anchor cable, and to tightly combine the support components with rock mass through anchoring agent to form a stable support system.
[0003] In related technologies, when drilling the roof, the rock fragments can fall naturally by gravity, and the cleaning work is relatively easy. However, when drilling the roadway floor, due to the influence of gravity direction, the rock fragments generated by drilling cannot fall freely and will remain in the drilling hole. If the drilling hole is not cleaned thoroughly, the remaining rock fragments will occupy the drilling space, so that the anchoring agent cannot be fully filled in the drilling hole, which seriously weakens the anchoring effect. Poor anchoring effect will lead to a decrease in the strength of roadway support, and in subsequent mining operations, it is extremely likely to cause safety accidents such as deformation and collapse of the roadway, which not only endangers the life safety of the workers, but also has an adverse effect on the mining progress and economic benefits.
