A joined pipe injector for the oil-field industry that is capable of handling strings of jointed pipe. The injector includes gripper block assemblies removably mounted to a pair of looping, sprocket-supported drive chains facing a pipe/tubing passage therebetween. The gripper block assemblies have self-adjusting pipe inserts biased with springs to grip tubing or pipe of constant nominal diameter or pipe having both nominal and secondary diameter including upset joints. An insert guide is provided at the end of the pipe/tubing passage to postpone contact between the pipe inserts and the pipe when the respective gripper block assemblies are moving with curving motion around the sprockets. The injector is designed to operate either independently, or in conjunction with a conventional work-over and/or drill rig.

A system for removing debris from a drill hole, the system comprising: a drill system comprising: a drill rod comprising a proximal end, a distal end a first lumen extending between the proximal end and the distal end, and a second lumen extending parallel to the first lumen, the first lumen being fluidically-isolated from the second lumen; a drill bit, the drill bit comprising: a proximal end for mounting to the distal end of the drill rod; a distal end configured to drill into a material so as to form the drill hole; at least one air channel extending between the proximal end of the drill bit and the distal end of the drill bit, the at least one air channel being configured to be fluidically connected to the first lumen of the drill rod when the dual channel drill bit is mounted to the drill rod; at least one vacuum channel extending between the proximal end of the drill bit and the distal end of the drill bit, the at least one vacuum channel being configured to be fluidically connected to the second lumen of the drill rod when the drill bit is mounted to the drill rod; a container fluidically connected to the second lumen of the drill rod; a compressor, the compressor being fluidically connected to the first lumen of the drill rod and fluidically connected to the container; wherein the compressor (i) pumps pressurized air through the first lumen of the drill rod such that the pressurized air passes through the at least one air channel of the drill bit and exits the distal end of the drill bit into the drill hole, and (ii) pumps air out of the container so as to generate a vacuum within the container, which vacuum is fluidically connected to the second lumen of the drill rod and hence to the at least one vacuum channel of the drill bit, such that pressurized air exiting the at least one air channel into the hole and debris in the hole enters the at least one vacuum channel, passes through the second lumen of the drill rod and into the container, such that the debris is collected in the container.

An automated pipe tripping apparatus includes an outer frame and an inner frame. The inner frame includes a tripping slips and iron roughneck. The automated pipe tripping apparatus may, in concert with an elevator and drawworks, trip in a tubular string in a continuous motion. The tripping slips and iron roughneck, along with the inner frame, may travel vertically within the outer frame. The weight of the tubular string is transferred between the tripping slips and the elevator. The iron roughneck may make up or break out threaded connections between tubular segments, the upper tubular segment supported by the elevator and the lower by the tripping slips. An automated pipe handling apparatus may remove or supply sections of pipe from or to the elevator. A control system may control both the automated pipe tripping apparatus and the elevator and drawworks.

A drilling device for coal mining is provided, including a placement board. The placement board is fixedly connected to a first support pillar and a second support pillar, and the first support pillar and the second support pillar are together fixedly connected to a transmission rod; the transmission rod is connected to support rods symmetrically distributed in a limited sliding manner, and the support rods symmetrically distributed are connected to a connecting rod in a sliding manner; the connecting rod is provided with grooves evenly distributed in a circumferential direction, the grooves are fixedly connected to pneumatic telescopic blocks, and the telescopic end of each pneumatic telescopic block is fixedly connected to an arc-shaped plate. The arc-shaped plate is extended in a circumferential direction to support the drilled hole close to the drill bit, preventing the collapse of the drilling wall close to the drill bit.
