Problems solved by technology

At present, the gas gushing collection device using the tunnel exhaust system adopts the injection of high-pressure gas or high-pressure water to expand the sealing body or capsule to block the borehole. Due to the technical requirements of plugging the borehole, it is necessary to inject high-pressure gas or high-pressure water. The device has a large volume and complex structure, and the plugging of the drill hole by the capsule cannot achieve the plugging effect required by the later project

Abstract

A gas discharge collecting device for drilling construction comprises drill hole sealing nests, a gas, water and slag discharge component, follow-up sealing components, a gas collecting component and a connecting pipe. The drill hole sealing nests and the follow-up sealing component are fixedly matched with two ends of the gas, water and slag discharge component. The connecting pipe is connected between the gas, water and slag discharge component and the gas collecting component. The gas discharge collecting device for drilling construction has no need for injecting high-pressure gas or water during drilling, a drilling machine can continuously operate in normal pressure state, the follow-up sealing component is rotationally sealed along with the drill rod, gas, water and slag discharged from the drilled holes are guaranteed to be in a closed cavity, gas is extracted out by negative pressure of a mine gas extraction and discharge system, and slag and water can flow out under the action of gravity. Drilling is safe and reliable, safety potential hazards are eliminated, drilling construction is guaranteed to carry out continuously and normally, and average drilling speed is greatly increased.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a gas gushing collection device for drilling construction. Background technique [0002] In mine coal mining projects, in order to ensure safe production before roadway excavation, advanced drilling must be carried out to find out the geological, hydrological and gas conditions ahead. In coal mining production, if the gas content in the coal seam exceeds the standard, the gas must be drained before mining is allowed. Drilling is a massive, basic, fundamental engineering measure. [0003] To implement drilling construction, the commonly used equipment is tunnel drilling rigs. This device is used in the drilling construction process of the tunnel drilling rig. Sometimes gas gushes out from the drilling hole, and the gas concentration in the local space near the drilling hole exceeds the standard. Sometimes the gas will flow out of the drilling hole The sudden spout in the ai...
