The mine electric coal drill security power controller circuit is composed of the trigger control circuit, maintain control circuit and control implementation circuit, and the circuit is shown as the chart. Trigger control circuit is composed of the drill handle switch S, resistors R1 ~ R5, diodes VD1, VD2, capacitors C1, C2 and transistor V1. Maintain control circuit is composed of the current transformer TA, capacitors C3 ~ C5, diodes VD3, VD4, resistors R6, R7 and transistor V2. Control implementation circuit is composed of the resistors R8, R9, capacitor C6, transistor V3, diode VD5, AC contactor KM and relay K. R1 uses 1 ~ 2W metal film resistor; R2 ~ R9 select 1/4W metal film resistors.
