Airflow reverse is a severe problem in an underground ventilation system. In addition, the airflow stability and safety production can be seriously affected by the problem of air velocity overrun in the roadways. In this ...

Fundamento y Métodos: En esta investigación se presenta el caso del análisis de un accidente del sector minero a través de 2 métodos distintos: 1) árbol de causas, 2) Feyer & Williamson. En el método del árbol de causas ...

An analysis of occupational accidents in the mining sector was conducted using the data from the Spanish Ministry of Employment and Social Safety between 2005 and 2015, and data-mining techniques were applied. Data was ...

An improved approach is presented to model the product particle size distribution resulting from grinding in high-pressure roll crusher with the aim to be used in standard high-pressure grinding rolls (HPGR). This approach ...

Methods and background: This review has done a comparison of the 3 types of workplace in the Spanish mining sector. The 3 workplaces considered are: mines, quarries and mineral processing plants. The 10 most frequent ...

Friction factor is a crucial parameter for assessing and modelling the ventilation system in underground mining. However, the development of a mine along its life can complicate the airflow supply required to the working ...

A model for High Pressure Grinding Rolls (HPGR) was developed in this work based on thewidely used Population Balance Model (PBM). This approach uses a variety of different func-tions one of which is the breakage distribution ...
