Abstract
The stress state of artificial monolithic pillars under the combined system of field development, which is affected by the rock pressure of hanging wall rocks and the active pressure of loose rock filling located in the chamber of the 2nd stage, was analyzed. As a result of calculations the optimum length of of the 1st stage chamber is 8 m, length of the 2nd stage II chamber is 40 m, hardening deposit strength is 3 MPa.
