For the efficient mining of potash seam III at the Starobinsk deposit, multi-slice longwall flow charts are developed. The flow charts involve sequential and simultaneous operations in the top and bottom longwalls within an extraction panel. The difference between these flow charts is mostly the time span between operations in the upper sylvinite layer and in the lower portion of the seam composed of two sylvinite layers with a halite parting. It is shown that the use of the concurrent multi-slice longwall flow chart allows high output of per extraction panel. According to the authors, sequential mining in longwalls off ers higher efficiency.
