| Abstract: | Based on the ore drawing theory study and with optimizing mining structural parameter as the cut-in point, wide-spaced mining theory was raised for the first time for Meishan Iron Mine and the mathematical model established, filling the domestic and foreign blank of pillarless sublevel mining theory. Based on this, laboratory test, compute simulation and on-site industrial test were made for verification.As a result, the main technical and economic indexes of the mine were raised in an all-round way. |
