Solid State Modulator for Plasma Channel Drilling
2008
2008 IEEE International Power Modulators and High-Voltage Conference
In addition to conventional mechanical and explosive drilling and demolition, drilling based on the use of pulsed electric power has been investigated intensively and recently commercial applications begin to emerge. With this method, the demolition of the rock is either performed by sonic impulses due to pulse discharges in water or by discharges directly through the rock, called plasma channel drilling (PCD). Due to the direct impact, the PCD method is more efficient. It is based on the fact
