Description
Technical Field
The utility model belongs to the technical field of coal mining drilling pipeline equipment, specifically a concentrate and bore regional pipeline structure of taking out and adopt.
Background
And after the tunneling working face tunnels in place in each cycle, installing DN377 or DN280 gas extraction pipelines in the head-on area of the working face for gas extraction. The pipeline is usually composed of a pipeline short joint and a gas collecting pipeline when being installed, and the gas collecting pipeline is usually a DN 377-DN 50-changing gas collecting pipe or a DN 280-changing DN50 gas collecting pipe. The DN50 gas collection port is perpendicular to the roadway bottom plate and is used for being connected with a pumping and extracting drill hole, a drill hole water drainage device is connected between the drill hole and the gas collection port, water pumped in the drill hole is drained through the water drainage device, and therefore the situation that accumulated water directly enters an extraction main pipeline to cause the reduction of the negative pressure of the drilling and extracting drill hole and the influence on the gas extraction effect is avoided. And a pipeline water drainage device is arranged at the upstream of the main pipeline in the centralized drilling area, and accumulated water in the main pipeline is drained through the water drainage device.
A water-rich area may exist in a local area, a small amount of water gushes may occur in a drill hole after a coal seam roof is found in part of drilling construction, and accumulated water in the hole can be pumped out to a drill hole water drainage device under the action of negative pressure. After the accumulated water in the drilling water drainage device is fully stored, if the water is not drained in time, the accumulated water can be sucked into the main extraction pipeline. Because DN50 gas collection mouth is located the main pipeline bottom, ponding when flowing in the main pipeline, will seal the gas collection mouth to influence drilling and take out the effect, will cause the drilling drill way no negative pressure when serious, the downthehole gas causes the environment gas unusual to gush out to the tunnel space.
Disclosure of Invention
The utility model discloses a solve above-mentioned problem, provide a concentrate and bore regional pipeline structure of taking out and adopt.
The utility model adopts the following technical proposal: the utility model provides a regional drainage pipeline structure of driling of concentrating, is including installing the drainage main line in the area of driling, and pipeline water drain ware I and pipeline water drain ware II are installed respectively to the terminal of drainage main line and gas collection stub upper reaches, are provided with a plurality of gas collection mouths on the horizontal direction of drainage main line, and the gas collection mouth horizontal direction sets up, and the gas collection mouth passes through the pipeline and communicates with the water inlet of drilling water drain ware, and the delivery port and the drainage drilling intercommunication of drilling water drain ware.
Further, the air collecting port is DN50 air collecting port.
Furthermore, the pipeline water drainage device I and the pipeline water drainage device II are located at the lowest point of the main extraction pipeline.
Furthermore, the height of the drilling water drainage device is lower than that of the pipeline water drainage device I and the pipeline water drainage device II.
When the extraction pipeline is installed in the centralized drilling area, the pipeline water drainage devices are respectively installed at the tail end of the main pipeline and the upstream of the gas collection short joint, and the hanging height of the pipeline is manually adjusted, so that the two pipeline water drainage devices are the lowest points relative to the main pipeline, and accumulated water can conveniently flow in the pipeline. When the installation gas collection is short-term, with DN50 gas collection mouth horizontal installation, when ponding is less than half pipeline volume in the main line, can not take out and adopt the negative pressure to the drilling and cause the influence. The gas collecting port is prevented from being blocked by accumulated water in the pipeline.
Compared with the prior art, the utility model discloses effectively having avoided effectively concentrating to have drilled the regional main road water of taking out and adopt and cause drilling to take out and take out the effect and reduce after, shortened and taken out the standard time of taking out, improved single cycle tunnelling efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the centralized drilling area extraction pipeline structure comprises an extraction main pipeline 6 installed in a drilling area, a pipeline water drainage device I1 and a pipeline water drainage device II4 are installed at the tail end of the extraction main pipeline 6 and at the upstream of a gas collection short section respectively, a plurality of gas collection ports 5 are arranged in the horizontal direction of the extraction main pipeline 6, the gas collection ports 5 are arranged in the horizontal direction, the gas collection ports 5 are communicated with a water inlet of a drilling water drainage device 2 through pipelines, and a water outlet of the drilling water drainage device 2 is communicated with an extraction drill hole 3.
The air collection port 5 is a DN50 air collection port. The pipeline water discharger I1 and the pipeline water discharger II4 are positioned at the lowest point of the main extraction pipeline 6. The height of the drilling water discharger 2 is lower than the height of the pipeline water discharger I1 and the pipeline water discharger II 4.
When the extraction pipeline is installed in the centralized drilling area, the pipeline water drainage devices are respectively installed at the tail end of the main pipeline and the upstream of the gas collection short joint, and the hanging height of the pipeline is manually adjusted, so that the two pipeline water drainage devices are the lowest points relative to the main pipeline, and accumulated water can conveniently flow in the pipeline. When the installation gas collection is short-term, with DN50 gas collection mouth horizontal installation, when ponding is less than half pipeline volume in the main line, can not take out and adopt the negative pressure to the drilling and cause the influence. The gas collecting port is prevented from being blocked by accumulated water in the pipeline.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
