But on the other hand, air drilling adopted air as the circular medium and so hydrocarbons like natural gas and oil mixed with air will cause downhole explosion if only the mixture reaches the explosion limit under any possible explosive condition, which will certainly threaten the safety during operations of air drilling.

The time limit test of ammunition burning and explosion on the condition of simulative fire was taken about representative ammunitions or component.

The author puts forward on-site handling plan, investigates the reasons susceptible to the burning and explosion accident combining the oxygen filter characteristics, verifies the design, fabrication, operation and maintenance and proposes the solution.
