The Research and Application of the Low Detonation Velocity and Elongated Source Charge

Huang Wenyao,Yan ShilongDept.of Chemical Engineering,Anhui University of Science and Technology(Anhui,232001)Lu Shuran,Kang DahaoBeijing Kelang Oil Technology Ltd.Co.(Hebei,072751)Feng Yide,Chen ShuanghuaHenan Geophysical Survey Team(Henan,460000)  
The structure and performance of the low detonation velocity and elongated source charge are designed and introduced, and explosive mechanism for the charge is also analyzed in this paper.The test results show that: the charge is stimulated to generate high energy and frequency and signal-to-noise ratio in the substrate of low speed of the longitudinal wave for coal seismic exploration, compared with TNT source charge of high detonation velocity.A new type of source charge is provided for coal seismic exploration of high resolution.It is worth to spread application.
