This paper is concerned with the path planning of coal mine robot. A new workspace model presented to describe complex environment. Thus, cost a composed not only distance but also some hybrid costs that can be linked criteria optimization. To overcome drawbacks conventional ant colony optimization (ACO) algorithm, an improved ACO algorithm developed tackle issues robot based on model. Some sim...

The purpose of this study was to survey the EMS (emergency medical services) personnel preparedness for major incidents in the underground mining industry in Sweden. Every year, a high number of incidents, workplace accidents and fires are reported from the Swedish mining industry. Taking care of patients located in an underground mine represents a challenge to EMS personnel. Today, knowledge a...

Over significant areas of the UK and western Europe, anthropogenic alteration of the subsurface by mining of coal has occurred beneath highly populated areas which are now considering a multiplicity of 'low carbon' unconventional energy resources including shale gas and oil, coal bed methane, geothermal energy and energy storage. To enable decision making on the 3D planning, licensing and extra...

background: assessment of prosthetic needs in a special population would aid in planning the oral health service programs. the aim of this study was to assess the dental prosthetic status and prosthetic needs in a sample of green marble mine laborers of udaipur, india.     methods: the study population comprised of 513 green marble mine laborers who were divided into four age groups (15-24, 25-...

The ability to execute true distributed and collaborative planning for amphibious operations, including ship-to-objective maneuver, selected intelligence and meteorological functions, and plan rehearsal is critical in the fast moving littoral/expeditionary warfare area. As part of an ongoing series of newly developed Tactical Decision Aids (TDA) for the Global Command and Control System – Marit...

We study a daily mine planning problem where, given a set of blocks we wish to mine, our task is to generate a mining sequence for the excavators such that blending resource constraints are met at various stages of the sequence. Such time-oriented resource constraints are not traditionally handled well by automated planners. On the other hand, the remaining problem involves finding node-disjoin...
