Selection of the Optimal Alternative of the Deposit Opening Applying the Decision-Making Process

The reason for opening deeper mining horizon is to preserve the volume of extraction, a smooth transition to a new horizon with the intention of mining state of existing stocks. In the proposal of opening will be maintain the current direction of transport (extraction of mineral, haulage of materials, lower) through bank to the existing plant equipment. Alternative proposals for solutions of opening new horizon will be limited to the range of main opening workings (hoisting shaft), including relevant hoisting equipment and objects immediately fasten on it. Other deeper horizon equipment outside the pumping station (filling station, transformer station, depot, level gangway, etc.) will be practically independent on the horizon and will be the same essentially in all cases. The proposal will be considered three alternatives: deepening of a shaft, sinking blind shaft and dip road. The best alternative will be recommended on the basis of the decision-making process.
