-. This roper discusses in *M tie process undetien to mitigate the effects of any fiture mine subsidence on prison structures proposed above old abandoned underground workings. The site for a proposed prison complex purchased by the State of Indiana was located in west-central Indiana and was undermined by an old abandoned room and pillar mine. The original plan for construcdon cmsisted of one ...

Yannan Coal Mine in Dayan Mining Area creatively utilizes water-preserving mining technology to block abandoned roadways build underground reservoirs and sedimentation tanks. It implements a zoned utilization management optimization technical plan for mine water, so that it can meet the needs of working face production surface domestic water use. This comprehensively recycles conservation makes...

Environmental Risk Assessment and Management (ERAM) is an approach, which is rapidly gaining popularity in South Africa. However, there are many different interpretations of the concepts and principles of ERAM and, unfortunately, a number of prevailing interpretations and wrong applications undermine the essential strengths of the riskbased approach. Examples of these misapplications are the ap...

We consider the multiple time period short-term production scheduling problem for a network of multiple open-pit mines and ports. Ore produced at each mine, in each period, is transported by rail to a set of ports and blended into products for shipping. Each port forms these blends to a specification, as stipulated in contracts with downstream customers. This problem belongs to a class of multi...

Rescue operation in coal mine is extremely dangerous due to several factors. It is particularly very harmful for the rescuers to get into the coal mine tunnel in disaster without the prior knowledge of environment because the subsequent explosions may likely to occur at any time it is therefore essential to detect the explosive environment details such as toxic gases, high temperatures and also...

We present an overview of the upcoming Microwave Anisotropy Probe (MAP) mission, with an emphasis on those aspects of the mission that simplify the data analysis. The method used to make sky maps from the differential temperature data is reviewed and we present some of the noise properties expected from these maps. An overview of the method we plan to use to mine the angular power spectrum from...

The mining of closed sequential patterns has attracted researchers for its capability of using compact results to preserving the same expressive power as traditional mining. Many studies have shown that constraints are essential for applications of sequential patterns. However, time constraints have not been incorporated into closed sequence mining yet. Therefore, we propose an algorithm called...

Abandoned coal mine spoils can result in severe pollution and have aesthetic on the local environment. A range of reclamation techniques is available for substrate but only through the use of vegetation to stabilize coal mine spoils can complete long-term rehabilitation be achieved. Experimentation has been undertaken at coal mine sites to attempt to elucidate and overcome limitations to vegeta...
