Due to their complex geological structure, it is difficult systematically analyze the surface subsidence of coal mines in southwest China, and factors that cause are also different from other mines. Focusing on problem caused by mining China’s mines, a grade evaluation system for constructed based analytic hierarchy process, ten indicators established perspectives disturbance structure. A matte...

Fatalities caused by highwall/spoilbank failure in the surface mines, coal and non-metal, increased to an alarming rate of seven during 1999. To determine the causes of slope failure and successful mining practices, the National Institute for Occupational Health and Safety undertook a study. The study included: 1. A review of accident statistics; 2. A review of Federal and state mining laws per...

The reconfigurable vibrating screen (RVS) machine is an innovative beneficiation machine designed for screening different mineral particles of varying sizes and volumes required by the customers’ through the geometric transformation of its screen structure. The successful RVS machine upkeep requires its continuous, availability, reliability and maintainability. The RVS machine downtime, which c...

Coal mines produce large amounts of excavated waste soils, known as spoils. These materials can cover vast areas, are typically dumped in heaps without any treatment, and difficult to exploit for engineering purposes because their significant variability. Efficient exploitation spoil poses challenges, related mainly the involved degree uncertainty. A small number studies have attempted characte...

The mining of underground coal resources often results in extensive damage to the ground surface, particularly China, which has a large amount resources. However, laws surface caused by deep and shallow are relatively different. This study analyzes difference induced its mechanism field measurement similar material simulation experiments. Surface is mainly manifested form cracks, can be categor...

Among the anthropogenic topographic signatures on Earth, open-pit mines are of great importance. Mining is of interest to geomorphologists and environmental researchers because of its implication in geomorphic hazards and processes. In addition, open-pit mines and quarries are considered the most dangerous industrial sector, with injuries and accidents occurring in numerous countries. Their fas...

A considerable amount of coal is lost due to the fires in underground/surface mines and it pollutes the natural environment because of the evolution of the pollutant gases like carbon monoxide, oxides of sulphur and nitrous fumes besides the unburnt hydrocarbons. Subsoil water loss in the area are severely damaging the strata. The movement of water overfire areas createfurther problems of low d...
