Underwater Drill Hole Demolition Work Dangerous Source Identification And Control

Scours, the harbor construction and in the submarine project construction practice in the route uses the submarine drill hole demolition work frequently.Because the submarine drill hole demolition work work condition is relatively difficult, the demolition work massive use blasting explosive, the detonation equipment, has the accident to cause the personnel casualty, the property damage risk is big.The underwater demolition produces the giant water shock-wave and the earthquake effect, peripheral and submarine constructs (construction) to the work place to build the thing, to anchor with the navigation ships, the aquaculture and the marine life destructive effect also more and more causes the people to take highly.Recognizes the submarine drill hole demolition work dangerous source, the appraisal submarine drill hole demolition work risk, takes the appropriate project technology measure and the management measure control dangerous source has the extremely vital significance.Submarine drill hole demolition work is engaged in which in view of the Liaoning colored reconnaissance research institute three branches, uses the fault tree, the event tree and so on the system safety hazard analysis method, has recognized the main accident pattern and the dangerous source which in the production process possibly occurs; Has discussed the water shock-wave, the air shock-wave and the stratum shock-wave production and the harm which the demolition creates; In harmed the analysis in the foundation under adding water the drill hole demolition work each main work link to carry on the production work condition risk appraisal in advance, has formulated the safety control examination and critique table, from the foundation safety control, the equipment installation security examination and critique, the work environment and the professional health 3 aspects has appraised the safety control condition; In the dangerous source identification and in the risk appraisal foundation, big fired a gun the accident in view of the risk, the demolition shock-wave and so on and the common mechanical injuries, the high place crashes, floods drowns the accident and so on to propose the dangerous source control technical measure, as well as the corresponding safety control measure aspect suggestion, with instructed the actual trouble-free service.
