Selecting a suitable pillar recovery method is one of the most important issues in the room and pillar mining. The main purpose of this study is to compare two methods for pillar recovery in Tabas central coal mine (TCM). Among the existing methods, the two methods, “Modified split and fender” and “Shortwall” are chosen for the numerical modeling. The three dimensional finite difference method ...
Abstract– A mine ventilation system is an important component of an underground mining system. It provides a sufficient quantity of air to maintain a suitable working environment. Therefore, the mine ventilation system should be kept at a highly reliable level and also be maintained at a very reliable level during the whole service time of the coal mine. However, in reality, failures of a mine ...
The robot mine clearing, based on cheap and widespread farming contrivances, provides considerably unusual prospects, which aim at enhancing safety, reliability and efficiency, to transform the terrorist anti-personnel mine into almost useless practice. The talk develops along the following lines: • to conceive and implement low-cost robotic equipment, assuring effective, safe and reliable demi...
A coalition of mine operators has used a variety of tactics to obstruct scientific inquiry and impede public health action designed to protect underground miners from diesel particulate matter. These workers are exposed to the highest level of diesel particulate matter compared with any other occupational group. This case study profiles a decade-long saga of the Methane Awareness Resource Group...
In order to comprehensively evaluate the employee satisfaction of mine occupational health and safety management system, an analytic method based on fuzzy analytic hierarchy process and 2tuple linguistic model was established. Firstly, based on the establishment of 5 firstgrade indicators and 20 secondgrade ones, the weight of each indicator is calculated and validated by method of FAHP and roo...
This paper deals with the issue of safety inside underground mines. The safety system designed based on wireless sensor network. The position of the different sensors inside underground mines is set by using analysis with ANSYS software. The safety system modeling in this paper is cost effective, energy saver , consistent, uninterrupted. This system performs automatic monitoring of different us...
