Optimization of staggered distance of coal pillars in multiseam mining: Theoretical analysis and numerical simulation

Energy Science &Engineering, Volume 9, Issue 3, Page 357-374, March 2021., 2021
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 mining. The staggered distance schemes of multiseam mining were optimized using the numerical simulation software FLAC3D.
