[0002] Well drilling is a mechanized and automated well drilling method for a mine shaft to pass through a deep, water-containing, unstable stratum. It is also the future development direction of deep shaft drilling. When the drilling shaft wall tube is lowered to the bottom of the borehole through the floating sinking process and the filling and cementing processes are completed, the subsequent construction of the horse head gate will be required. The horse head gate structure is a key part of the mine. It is a support structure located at the intersection of the vertical shaft and the tunnel. The surrounding chambers are dense and the structure is highly complex. During the construction of the horse head gate, it is necessary to drill a hole at the bottom with a drilling rig and reinforce it with grouting in the borehole to enhance the stability and safety of the horse head gate structure. However, due to the heavy drilling rig, when the drilling rig needs to be moved to switch the drilling position, it consumes manpower and the operation is inconvenient, resulting in low construction efficiency.
