  • Sabinet Mining method selection by multiple criteria

    Mining method selection is the first and most important problem in mine design. In this selection some of the parameters such as geological and geotechnical properties, economic parameters and geographical factors are involved. The mining engineer must balance the input parameters and select the method that appears to be the most suitable; mining method selection is both an art and a

  • Underground mining method selection and preliminary techno

    First phase is the mining method selection on technical suitability to the orebody; for which two methods are. The UBC method is applied first resulting in the selection of the area of sublevel stoping methods. Later a new technique is introduced to optimize the mining method selection process and to control the wide spectrum of mineral deposits.

  • Method Selection A Numerical Approach

    INTRODUCTION In this paper, a numerical process for selecting a mining method, with the emphasis on underground mass mining techniques, such as caving, induced caving, and stoping, is proposed.

  • Here are the Types of Underground Mining and Their

    This method is called underground mining, whose types are explained below. Room and Pillar Mining. In this method, mining is carried out in an ore deposit, leaving behind some of the ore in the form of columns to support the roof and prevent it from collapsing. Thus, it results in the formation of spaces called ‘rooms’, where the ore is

    Mechanized mining technical process (MMTP) related to the control method of the shearer is a vital process in thin coal seam mining operations. An appropriate MMTP is closely related to safety, productivity, labour intensity, and efficiency. Hence, the evaluation of alternative MMTP is an important part of the mining design. Several parameters should be considered in MMTP evaluation, so the

  • What are the main methods of mining? American

    There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
