Аннотация | In Russia, the mineral resource base is used on a particularly large scale, and the mining complex is essentially a basic industry for the maintenance and development of our country's economy. It determines the need for a careful and responsible attitude to our subsoil riches – mineral deposits. In this regard, minimizing the level of losses and dilution of ore becomes one of the key requirements for the stoping technology. The highest levels of ore losses in an array are formed in mining areas of ore bodies contact with the host rock mass as a result of a mismatch between the mining contour and the geological contact surface. The complexity of the contact of ore and host rocks is usually characterized by the so-called "stochastic contact area". The technological complexity of ore mining at the ore-rock contact is determined by variability of geometric parameters of the "stochasticity zone" on the geologic contact plane. In this article, the issues on setting of losses and dilution when mining the near-contact zones are discussed. The method of calculating the specified values of losses and dilution in the stochasticity zone is provided. The authors developed an algorithm for determining the profile of contact. In the stochasticity zone, a contact can take a rectangular, sinusoidal, sawtooth or straight profile. The research showed the influence of contact profile on the level of losses and dilution of ore; the formulas for calculating the ratios are provided. When using the proposed method, it is possible to most easily and reliably determine the specified values of ore losses on the contacts. | |
