Queensland Mining has a strong focus on safety performance, but risk management of health, including Musculoskeletal Disorders (MSDs) continues to have a lower priority. The reliance on individual screening of workers and lower level approaches such as manual handling training is part of the coal mining 'culture'. Initiatives such as the New South Wales and Queensland Mining joint project to de...

Original scientific paper Mining near the fault structure can easily lead to the fault activity and induce serious geological disasters, posing a serious threat to coal mine safety production. To reveal the surrounding rock activity characteristics induced by near-fault mining, taking Qixing Coal Mine in China as the engineering background, the contrastive analysis of the microseismic events in...

The conventional practice in open cut coal strip mining has been to blast the overburden or coal layers in separate blast events. This is done in order to maximise the benefits from throw blasting and also to limit coal losses. Each blast event usually has a particular design of hole diameters, burdens and spacings, explosive charges and blast timing in order to achieve the required blast outco...

Surface coal mining creates more air pollution problems with respect to dust than underground mining . An investigation was conducted to evaluate the characteristics of the airborne dust created by surface coal mining in the Jharia Coalfield. Work zone air quality monitoring was conducted at six locations, and ambient air quality monitoring was conducted at five locations, for a period of 1 yea...

INTRODUCTION There is still interest in a unified methodology to quantify the mass of particulate material emitted into the atmosphere by activities inherent to open-pit mining. For the case of total suspended particles (TSP), the current practice is to estimate such emissions by developing inventories based on the emission factors recommended by the USEPA for this purpose. However, there are d...

Coal is the most highly used source of energy for generating power in the world. Although, it has adverse environmental impacts (Weart, 2003), it is so widely used mainly because it is relatively cheap, abundantly available and readily fits with traditional power generation technologies. It is extracted from mines using both underground and surface mining techniques – either of them having adva...

Mining for coal and its utilization have various impacts on the surrounding environment. Huge volumes of waste materials which are by-products of both the underground and open cast coal mining, pose one of the major environmental hazards in addition to air pollution caused by coal burning in power plants in the Czech Republic. Some of these risks could be reduced when having accurate and compre...

This article examines the social and material politics of coal, focusing on mobilizations against opencast mining in the United Kingdom and Indonesia. Contested spaces and practices elicited by coal extraction provide important openings through which to understand how ‘hydrocarbon modernity’ is experienced and entangled with different processes of neoliberal capitalism. We investigate resistanc...

Jharia coal-field holds unequivocal importance in the Indian context as it is the only source of prime coking coal in the country. Haphazard mining over nearly a century has led to environmental changes to a large extent such as degradation in the quality of air, water, soil, changes in landform, land-use/land-cover and vegetation distribution. Environmental impact assessment is a process to as...
