By using above-mentioned technical proposal, air bag is installed window and is defined to the position of top broken height pressuring gasbag, when top broken height
When pressuring gasbag expands, due to the position restriction of air bag installation window, top broken height pressuring gasbag is not susceptible to move；Air bag mounting groove is to pushing away
The position of dynamic high-pressure gasbag is defined, and when pushing high-pressure gasbag expansion, due to the position restriction of air bag mounting groove, is pushed high
Pressuring gasbag is not susceptible to move, so that top broken height pressuring gasbag and promotion high-pressure gasbag can preferably realize that top is disconnected and pushes
Effect.
The utility model is further arranged to: the coring shell is far from solid on the side inner wall for pushing high-pressure gasbag
Surely it is connected with rock pillar deck.
By using above-mentioned technical proposal, drives rock pillar mobile towards rock pillar deck after pushing high-pressure gasbag expansion, pushing
Under the collective effect of high-pressure gasbag and rock pillar deck, rock pillar is fixed in coring shell by relatively stable.
The utility model is further arranged to: being provided with air pressure monitoring device on first admission line.
By using above-mentioned technical proposal, it although it is understood that top broken height is calmed the anger by the air pressure in the first admission line of detection
It is timely to facilitate worker so that it is determined that whether top broken height pressuring gasbag has realized the disconnected operation in top to rock pillar for intracapsular pressure change
Next step operation is carried out, the efficiency of drilling is improved.
In conclusion the utility model has the following beneficial effects:
By setting top broken height pressuring gasbag, push high-pressure gasbag in and pressure control component, pass through pressure control component pair
Top broken height pressuring gasbag and promotion high-pressure gasbag are controlled, so that realization is disconnected to the top of rock pillar and fixed, to enable worker
Rock pillar is taken out from drilling conveniently, improves the efficiency of drilling.
