We examine the real effects of mandatory, non-financial disclosures, introduced into securities regulation under the Dodd-Frank Act, which require firms to disclose their mine-safety records in their financial reports. Most, if not all, of the information included in these disclosures was already publicly available, which allows us to examine the incremental effects of including the information...

We examine the real effects of mandatory disclosures on social responsibility, which require SEC-registered mine owners to include their mine-safety records in their financial reports. These safety records are already publicly available elsewhere, which allows us to examine the incremental effects of including information in financial reports. Comparing mines owned by SEC-registered issuers to ...

The safety issue of coal mining engineering is very important to coal industry. According to our coal mine enterprises' safe characteristics, this paper analyzed the risk factors of coal mining engineering and studied the safety problem of “humanmachine-environment” system. The risk factors of coal mining engineering are divided to natural geological factors, personnel factors, equipment factor...

A common thread throughout our discussions was the importance of good operations management to success in a very competitive market environment. Mining is not unique: Since the 1980s, efforts to improve management (epitomized by benchmark companies such as General Electric and Intel) have been undertaken throughout the business community. Improving mine organization and management practices has...

Reactor control and safety systems are discussed with emphasis on safety considerations. Consideration is given to the importance of reactor characteristics, control and safety system characteristics, the operational program of the reactor, and credible accidents, in a determination of safety of operation. Ecperience with research reactor control and safety systems has led to the development of...

The purpose of this paper is to describe a feasibility prototype of a Computer-Aided Instruction (CAI) system, developed for mining engineering students and mine and safety personnel to teach the complex interrelationships between a mine ventilation system and a mine fire. The system employs an artificial intelligence technique to increase students' involvement in the learning process of "inter...

Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...

The future success of Navy-Marine Corps operations in the extended littoral battlespace will depend critically on organic mine countermeasure capabilities. A battlegroup commander will require tools to rapidly detect, classify, and identify mines and form a tactical picture of mined areas, so a decision can be made to punch through the minefield, avoid it, or wait for dedicated mine countermeas...

In all over the world, mining is considered as a high-risk activity that is pregnant with serious disasters not only for miners, engineers, and other people into it, but also for people who live near the mines. In this article, our main purpose is to examine some major mine disasters and safety in mines and the case study is a coal mine in Turkey. Safety in mines is one of the most important is...

According to the poor image quality of the monitoring system in coal mine monitoring, an integrated image clarity method was presented which using adaptive multi-level noise reduction median filter based on the direction in the spatial domain to denoise the image first, then using multi-wavelet transform to enhance the low-light image in the transform domain. This integrated approach combines t...
