ABSTRACT
Modern oil and natural gas energy must be transported over long distances through pipelines. There are over 2,000,000 km transmission pipeline in the world, and about 75% of natural gas pipeline is underground. China had built over 10,000 km natural gas pipeline as well. Long distance pipeline can hardly avoid passing hazardous areas such as chemical plants, explosive storage, blasting engineering and so on. These pose potential hazards natural gas pipeline. Blasting near the pipelines is the most common hazard, as this might lead to leakage through rupture, and eventually to gas explosions as in the case of the Ural Mountain tunnel disaster [Du, 2005].
