Method and apparatus for increasing the yield in a deposit

摘要

A method for increasing the yield of a deposit including a rock which including at least one valuable mineral to be exposed by comminuting the rock and at least one further mineral, may include the following steps: performing a boring operation using a boring device prior to extracting the rock, determining at least one predetermined boring parameter for the boring device, determining at least one measured value characterizing a current boring behavior of the boring device, and performing a computational elimination of a dependency of the at least one measured value on the at least one boring parameter, wherein at least one rock texture-dependent characteristic value is obtained, and wherein the at least one characteristic value is used as a measure for a mineral particle size of the at least one valuable mineral in the rock and for setting an optimum degree of comminution when comminuting the rock.

1. A method for increasing the yield in a deposit comprising a rock which comprises at least one valuable mineral which is to be exposed as a result of the rock being comminuted, and at least one further mineral, the method comprising:
performing a drilling operation using a drilling tool prior to the rock being extracted, acquiring at least one predefined drilling parameter for the drilling tool, acquiring at least one measured value characterizing a current drilling behavior of the drilling tool, performing a computational elimination of a dependency of the at least one measured value on the at least one drilling parameter, which provides at least one rock-texture-dependent characteristic value, and using the at least one rock-texture-dependent characteristic value as a measure for a grain size of the at least one valuable mineral in the rock and for setting a target degree of comminution for a comminution of the rock.
