Description

Technical Field

[0001] The utility model relates to the technical field of gas management, in particular to a gas management anti-spray hole device. Background Art

[0002] During the coal hole construction and coal seam drilling process, a large amount of gas is ejected from the coal rock cracks and drill holes, causing gas blowout holes, which not only makes it impossible to continue drilling construction, but also easily causes gas overlimit in the excavation tunnel and causes gas explosion; according to statistical data in recent years, among various coal mine accidents, coal mine accidents caused by gas explosions account for about 47% of the total number of coal mine accidents. How to effectively control gas leakage has become an issue that all departments in coal mines are very concerned about and pay attention to.

[0003] For example, the announcement number CN218509404U discloses a gas control anti-blowout hole device, comprising: a base, a puncher, a sealing gasket, a mobile chassis, and a mobile chassis stabilizing structure. The mobile chassis is fixedly installed on the bottom surface of the base, and the mobile chassis stabilizing structure is fixedly installed at the four corners of the bottom of the mobile chassis. The puncher is slidably installed on the top surface of the base, and the front end of the puncher is detachably installed with a sealing gasket, and the sealing gasket is threadedly connected to the front end of the puncher. The sealing gasket structure installed in the anti-blowout hole device in the prior art is reformed into a detachable installation structure to ensure that the sealing gasket is easy to disassemble and replace. At the same time, the supporting stabilizing structure of the blowout hole device is reformed, replacing the prior art method of using only mobile wheels to provide support for the device, thereby preventing the displacement of the device and thus the deviation of the drilling position.

[0004] However, when this type of gas control anti-blowout hole device is used, although it can perform drilling operations well through a drill, the pre-positioning support effect for the position to be drilled is not high during drilling, so that when the drilling rod contacts the drilling position, the drilling position will deviate due to vibration, thereby reducing the accuracy of the gas control drilling position.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a gas control anti-blowout hole device is proposed. Utility Model Content
