Rock burst prevention rescue escape trolley based on drilling and blasting method and using method

Abstract

The invention discloses a rock burst prevention rescue escape trolley based on a drilling and blasting method and a using method, and relates to the field of underground engineering. The rock burst prevention rescue escape trolley comprises a foundation framework, a rescue protection framework and an escape protection framework; the foundation framework comprises a truss structure formed by welding I-shaped steel, an upper straight ladder and a lower straight ladder; the rescue protection framework comprises hydraulic rotating rods, protection steel plates and a rescue capsule; the two sides of a first-layer working face and the two sides of a second-layer working face are connected with the protection steel plates through the hydraulic rotating rods correspondingly; the rescue capsule is located between the second-layer working face and a third-layer working face; a rescue hole is formed in the third-layer working face; the escape protection framework comprises an escape hanging ladder and an escape hole; the escape hole is formed in the second-layer working face and located in the rescue capsule; and during escape, the escape hanging ladder is hung at the escape hole. The rock burst prevention rescue escape trolley can resist damage generated when rock bursts of different grades happen, and safety protection and escape guarantees are provided for constructors at the first time when the rock bursts happen.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to a rockburst prevention and escape trolley based on a drilling and blasting method and a use method thereof. Background technique [0002] At present, the face construction based on the drilling and blasting method mostly adopts mechanical drilling, which can minimize the loss of staff in the face of geological hazards such as rockbursts. There is also the case of manual drilling construction, because there are large errors in geological detection, and the actual occurrence of rockbursts during underground engineering construction is obviously more serious than the survey data. If the construction organization design is replaced, the loss is huge, so it is necessary to Continuation of the original construction method of manual drilling. For the convenience of construction, most of the existing working face trolleys have less consideration for the prevention of rockbursts. G...

[0002] At present, the face construction based on the drilling and blasting method mostly adopts mechanical drilling, which can minimize the loss of staff in the face of geological hazards such as rockbursts. There is also the case of manual drilling construction, because there are large errors in geological detection, and the actual occurrence of rockbursts during underground engineering construction is obviously more serious than the survey data. If the construction organization design is replaced, the loss is huge. Therefore, it is necessary to Continuing the original manual drilling construction method

For the convenience of construction, most of the existing working face trolleys have less consideration for the prevention of rockbursts. Generally, they choose to wait for the rock mass to stabilize after excavation, which seriously restricts the progress of the construction period. In addition, the rock mass Bursts are instantaneous and destructive, and the time of rockbursts is extremely difficult to predict. It will cause strong damage within minutes or even seconds, and the life safety of the staff is seriously threatened. Therefore, a trolley that can deal with different levels of rockbursts is urgently needed. provide security
