The drilling holes for coal uncovering in the shaft are all downward holes, and the drilling volume is large, and the construction period is tight. When constructing in the shaft, there is no fulcrum above the drilling rig, and the pressure column cannot be hit. In addition, after the drilling holes that have been constructed on the bottom plate are closed, the exposed sealing pipes and extraction pipes will affect the movement of the drilling rig and the drilling construction, seriously affecting the safety and efficiency of drilling.

[0011] The present application sets up a steel ring base, on which the drilling rig is installed, and sets up several layers of steel rings in sequence from the inside to the outside, and sleepers and road logs are set between the several layers of steel rings and the ground for support, and the gap left between the steel rings and the ground is just enough to lead out the extraction pipeline, thereby avoiding the influence of the extraction pipeline on the drilling construction; and the drilling rig is installed on several layers of steel rings, and when moving, it only needs to be pulled on the steel rings. The friction on the steel rings is small, and pulling is more convenient, saving time and effort.

[0012] As a further solution of the utility model: the fourth layer of steel ring is evenly divided into two arc segments, and the gap between the two arc segments is 200 mm.

[0013] As a further solution of the utility model: the third layer of steel ring is evenly divided into three arc segments, and the gap between every two of the three arc segments is 200 mm.

[0014] As a further solution of the utility model: the second layer of steel ring is evenly divided into four arc segments, and the gap between every two of the four arc segments is 200 mm.

[0019] Firstly, in this application, by setting a steel ring base, the drill is installed on the steel ring base, and several layers of steel rings are arranged in sequence from the inside to the outside. Sleepers and wooden beams are arranged between the several layers of steel rings and the ground. The gap left between the steel rings and the ground can just lead out the extraction pipeline, avoiding the influence of the extraction pipeline on the drilling construction. Moreover, the drill is installed on several layers of steel rings. When moving, it only needs to be pulled on the steel rings. The friction on the steel rings is small, and it is more convenient to pull, saving time and effort.

[0020] Secondly, in this application, a "sleeper + steel ring + ground anchor" combined device is installed on the shaft floor. This device forms an integral body between the steel ring and the floor through the ground anchor and the anchor chain, making the steel ring serve as a base for fixing the drill. The drill can be fixed and moved on the steel ring, solving the problem that the pressing columns cannot support during the shaft construction. And the steel ring is padded with sleepers to leave enough space between the steel ring and the floor. The extraction hoses of the drilled holes that have been constructed are arranged under the steel ring, avoiding the influence of the extraction pipeline on the drilling construction.
