A network model to optimise cost in underground mine design
Abstract: This paper examines the problem of designing an underground mine so as to optimise the development and haulage costs. It focusses particularly on the costs underground mines, but the cost of these methods for bulk, base-metal mines is significantly higher than for narrow reef mines; thus, the technology may not be Mine design impact on operating and capital costs

The practice of mine ventilation engineering ScienceDirect
Good practice means incorporating a ventilation system that fulfills the legislative requirements even if there is no mine inspectorate to ensure the system is in compliance. Being complacent in the practice of mine ventilation can have severe, and possibly deadly, consequences. 2. Current trends in mine ventilation.We have experience designing backfill systems, ventilation systems, development entries, dewatering systems, pump stations, and haulage systems.

Heat stress in deep hot mines is a factor that often determines the possibility of technical mining of natural resources. One of the solutions enabling miners to work in such mines is air cooling. Cooling systems vary, and their selection depends on the type of mine and the mining methods used. Limited air cooling capabilities exist in Measuring Transport Time of Mine Equipment in an Underground Mine Using a Bluetooth Beacon System Jihoo Jung and Yosoon Choi * Department of Energy Resources Engineering, Pukyong National University, Busan 608-737, Korea; haksu8874@gmail * Correspondence: yspower7@gmail or Measuring Transport Time of Mine Equipment in an Underground Mine

Dewatering management is critical for new mines
Dewatering management is critical for new mines. A major consideration when starting an open pit or underground mine is to ensure that it will have the most efficient, cost-effective, and low-carbon system for controlling water whether from under the ground or rainfall.

Each mining site is different, so the nature and the extent of the flooding risk differs, but the demand for effective underground mine dewatering However, the productivity and operating cost of an underground mine are heavily dependent on the mining method employed, the rock conditions, the quality and underground mining equipment is specialized and expensive.

Moving towards deep underground mineral resources
Although progresses have been made to ensure that rock temperatures are cooled to <25 °C, thanks to the advances in underground ventilation and cooling systems, the cost of ventilation and cooling accounts for 30%–40% of total electricity costs in an underground metalliferous mine (Schutte, 2014; Mochubele, 2014).Orebody Modelling and Strategic Mine Planning Spectrum Series Volume 14 123 OPTIMISATION IN THE DESIGN OF UNDERGROUND MINE ACCESS Existing decline Optimised new development FIG1 This figure, from a live case study, illustrates the capacity of UNO to design an optimal network extending an existing mine and accessing Optimisation in the Design of Underground Mine Access

IMPORTANT BASICS OF MINE VENTILATION AND COOLING PLANNING
It is essential to know the long-term needs in designing for the short-term [and vice-versa]. In addition, the capital costs of vent/cooling equipment can be so high that an optimised phase-in strategy can be almost as important as correct equipment sizing. The vent/cooling requirements must be taken into account in the early planning stagesThis paper presents a method for optimally designing a decline together with its associated vent raise. We establish a sufficient condition on the optimal (least cost) location of the vent raise(PDF) Optimal design of an underground mine decline with an
