Abstract
The utility model discloses a collecting device used in drilling a hole for underground gas drainage in a coal mine. The collecting device comprises a container, openings are formed at the corresponding parts of the front and the back faces of the container and having the same diameter as the drill bit, and a pipe connector is arranged on the upper surface of the container and used for gas drainage. When in use, the collecting device is fixed on a laneway's side in the hole-drilling position, the drill bit passes through the openings to drill, and the collecting device is communicated with the gas drainage pipeline by a hose through the pipe connector. The gas generated during the drilling construction is completely collected in the device and then sucked into the gas drainage main pipeline, thereby avoiding the problem of gas accumulation in the laneway after outburst under the gas pressure.
Description
Technical field
The utility model relates to coal mine downhole safety equipment.
Background technology
Higher and exist the mine of certain gas pressure all to set up gas drainage system at some gas bearing capacities, during extraction, need in the coal seam, construct firedamp taking-out discharging drilling.If when running into " cherry coal band " or geology fold and fault zone in the drilling construction process, gas will discharge in holing fast, forms " spray orifice " phenomenon.Gas ejection causes that gas seriously transfinites in the tunnel, brings threat to safety in production.Therefore, be sought after a kind of device that the gas of ejection can be collected in together.
Summary of the invention
The utility model provides a kind of gathering-device for the gas that construction under the coal mine discharges during firedamp taking-out discharging drilling.
The technical scheme that the utility model is taked is: it comprises a container, is processed with the hole identical with bit diameter at the front-back corresponding position of container, is processed with an interface tube that draws out methane on container.
The utility model has the advantages that: during use, help in the lane that this device is fixed on the boring tapping, and the rig drill bit passes hole perforating again, by interface tube flexible pipe and gas drainage under suction pipeline connection.The gas of gushing out in the drilling construction process all accumulates in this device, and is inhaled in the gas drainage under suction main line, thereby avoids because the gas pressure effect causes the tunnel methane accumulation phenomenon behind the spray orifice.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data: 1-container; The 2-hole; The 3-interface tube;
The specific embodiment
As shown in Figure 1, gathering-device of the present utility model comprises a container 1, is processed with the hole identical with bit diameter 2 at the front-back corresponding position of container 1, is processed with an interface tube that draws out methane 3 on container 1.
During use, help in the lane that the gathering-device of utility model is fixed on the boring tapping, and the rig drill bit passes hole 2 perforating again, by interface tube 3 usefulness flexible pipes and gas drainage under suction pipeline connection.
Claims (1)
1. the gathering-device when drawing out methane boring under the coal mine is characterized in that it comprises a container, is processed with the hole identical with bit diameter at the front-back corresponding position of container, is processed with an interface tube that draws out methane on container.
