Through the investigation of more than 100 domestic mines, the main problems of the current mine power supply intelligence and unmanned construction are summarized, and the hidden safety hazards brought by these problems to mine safety are analyzed. At the same time, the “six integration” targeted solution is proposed, which can provide a more comprehensive reference for the intelligent power supply and unattended construction of coal mines. This solution is conducive to realize all-round anti-overstep tripping (including short circuit to prevent leap-level, switch rejection to prevent leap-level, voltage fluctuation to prevent leap-level and fixed value mismatch to prevent leap-level, etc.), accurate grounding fault line selection (accuracy rate 100%), low voltage leakage accurate leakage selection (accuracy rate 100%), leakage remote key test and comprehensive remote control and other functions.
