We propose a simple generalization of the Brennan-Schwartz approach to real option valuation of a mining project that incorporates disaster risk using a Poisson point process to model arrivals. Using techniques from the field of robust performance analysis, we are able to calculate upper and lower bounds over all the probability models within a certain distance from the original model. We sugge...

On the 13th of May 2014, 301 miners lost their lives in a coal mine explosion Soma, Turkey. A field study was conducted by volunteers under roof EMDR Humanitarian Assistance Programs: Trauma Recovery (EMDR-HAP-TR) organization. All interventions this were aimed to help victims disaster. Furthermore, assess effectiveness intervention, specifically Group Protocol (EMDR-GP) with Children and Careg...

In the deep mining, the disaster dynamic of coal petrology and gas becomes increasingly serious, dynamic coupling of coal gas disaster grows in number. However the traditional method of predicting is limited. In order to evaluate the dynamic disaster hazard level of the coal face in the deep mine, a fuzzy hierarchy comprehensive evaluation model of the coal petrology dynamic disaster on the coa...

In recent, the placement of backfill in underground mines has emerged as a new paradigm in research as it not only improves safety but also allows disposal of byproducts including coal ash. In this regards, this paper addresses the backfilling challenges in limestone mine to prevent sinkhole and subsidence. Limestone mines, generally regarded as being safer than coal and metal mines, have been ...

Reclamation under the strict requirements of the federal Surface Mining Control and Reclamation Act of 1977 requires a high level of knowledge of plant growth r e q u i r e m e n t s in r e l a t i o n to geochemical factors on each mine site. A desirable reclamation goal would be to consider all feasible alternatives for creating productive soils and attractive landscapes. The raw materials fo...

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...

The mine ventilation optimization and airflow control are the mine ventilation system's two important aspects, good ventilation optimization design can deliver fresh air to establish good work environment and provide a scientific and reliable basis to prevent disaster. Based on the air distribution request of the mine ventilation network, carries on the optimized computation to the mine ventila...

On March 11, 2011, Japan's northeast Pacific coast was hit by a gigantic earthquake and subsequent tsunami. Soma City in Fukushima Prefecture is situated approximately 44 km north of Fukushima Daiichi Nuclear Power Plant. Soma General Hospital is the only hospital in Soma City that provides full-time otolaryngological medical care. We investigated the changes in new patients from one year befor...

The great earthquake of 11 March 2011 and resulting tsunami caused serious damage to various areas of the Pacific coast in northeast Fukushima, and all the residents faced fears of meltdown of the reactors at the Fukushima Daiichi Nuclear Power Plant. One of the most seriously affected areas was the district of Soso, located in the northeast part of Fukushima prefecture, with 12 municipalities ...
