An apparatus, rock drilling rig and drilling method. The apparatus (A) provides position control data (39) for controlling positioning a rock drilling unit (4) of a rock drilling rig (1) for drilling transverse drill hole patterns (13) to an underground tunnel (7). The apparatus comprises a teaching feature (33) for gathering data on manually controlled movements (38) at the location of the drill hole pattern and to thereby detect a movement path which is collision free. The data on the taught collision free movement path (19) is implemented when controlling the rock drilling unit during an actual drilling phase.

The invention discloses an underwater pebble covering layer drilling method which comprises the following steps that S1, a variable-diameter casing pipe is pressed into water in a hydraulic pressing-in mode, the bottom of the variable-diameter casing pipe penetrates through a pebble layer and abuts against underwater rock, and the variable-diameter casing pipe comprises a large casing pipe body and a small casing pipe body which are connected with each other; s2, a drill rod is inserted into the variable-diameter casing pipe, and the drill rod is started; and S3, firstly crushing the cobblestones by the drill rod, and then drilling holes in the underwater rock. The variable-diameter casing pipe can penetrate through a cobblestone layer through hydraulic pressing, and the problem that a traditional casing pipe is difficult to penetrate through the cobblestone layer is solved. The large sleeve and the small sleeve form the variable-diameter sleeve, when the variable-diameter sleeve is lowered, the influence of water flow on the large sleeve is small, when the small sleeve penetrates through the cobblestone layer, the diameter of the small sleeve is smaller, the small sleeve can be inserted into the cobblestone layer more easily, the junction of the small sleeve and the large sleeve is in smooth transition, and the large sleeve can be inserted into the cobblestone layer along with the small sleeve conveniently. The small casing pipe is more attached to the drill rod, accurate guiding is conveniently provided for the drill rod, and work of the drill rod is facilitated.

The present application relates to a kind of solid deflagration expansion fixed type ultrasonic wave drilling anchoring device and method, belong to ultrasonic wave drilling anchoring technical field.Solve the problem of insufficient anchoring force.It includes feeding device and drilling anchoring device, the feeding device is established with drilling anchoring device cooperation, feeding device is used to drive drilling anchoring device, drilling anchoring device is used to realize fixed.The present application when reaching certain drilling depth, solid fuel in the end of drill pipe cavity is ignited by electrode, ignites solid fuel nitrocellulose, occurs violent combustion and explosion, produces a large amount of energy, and the end of drill pipe is extruded and deformed;Deformed expansion cavity will extrude the inner wall of borehole, produce certain expansion force, provide larger effective anchoring force for the whole device, realize the fixation of the whole device, provide larger anchoring force for sampler under simple structure.

An apparatus, rock drilling rig and drilling method is provided. The apparatus provides position control data for controlling positioning a rock drilling unit of a rock drilling rig arranged for drilling transverse drill hole patterns in an underground tunnel. The apparatus includes a teaching feature for gathering data on manually controlled movements at the location of the drill hole pattern and to thereby detect a movement path, which is collision free. The data on the taught collision free movement path is implemented when controlling the rock drilling unit during an actual drilling phase.

The invention discloses an integrated blast hole automatic drilling and charging system, which belongs to the technical field of automatic blasting equipment and comprises an advancing mechanism, a downward drilling device, a continuous charging device, a wireless detonator inserting device and an automatic cartridge feeding device. And the advancing mechanism advances on the ground. And the downward drilling device is used for drilling a vertical blast hole underground. And the continuous charging device is used for clamping and bearing the cartridges which are vertically arranged, moves to the position above the drilled hole along with the feeding mechanism and puts the cartridges into the drilled hole. And the wireless detonator inserting device is used for inserting the detonator into the clamped cartridge. And the automatic cartridge feeding device is responsible for supplementing cartridges to the clamping position. According to the device, the processes of drilling, charging, detonator mounting and the like are integrated, mechanization and automation of blasting operation are achieved, the labor intensity of workers and potential safety hazards can be remarkably reduced, and the operation efficiency and reliability are improved.
