The utility model discloses a heavy -calibre high -pressure natural gas pipeline blasting seismic wave measurement system, including laying near a plurality of seismic wave sensors natural gas line, the sensor be divided into if the dry channel array, every via array uses the originated crack point of blasting on natural gas line to be the initial point to be different contained angles with the natural gas line direction. The utility model discloses a seismic wave sensor array arranges near heavy -calibre high -pressure natural gas pipeline, along with pipeline contained angle equidirectionalarranging not, measure the space intensity distribution characteristic that obtains the seismic wave to analogize with this parameter, under the limited prerequisite of number of sensors, obtain the seismic wave parameter of whole area of explosion intra -area.
