Optimization of staggered distance of coal pillars in multiseam mining: Theoretical analysis and numerical simulation
Abstract Aimed at solving problems related to water retention and loss reduction in multiseam mining, a mechanical model of staggered distance mining was established. First, elastic and plastic slip line field theories were used to calculate the reasonable staggered distance expressions of multiseam...
