Bu çalışmada, açık ocak maden faaliyeti yürüten bir firması çalışanlarının iş sağlığı ve güvenliği verimliliği arasındaki ilişkiyi incelemiştir. Maden firmasına ait saha içerisinde önceden yaşanan kazalar alınan önlemler incelenmiştir. Demografik özellikler, verimlilik durumları ile ilgili anket formları düzenlenmiştir. İlgili formlar 56 kişiye uygulanmış tamamı değerlendirmeye alınmıştır.&#x0D...

A detailed hydrogeochemical study was performed in the Wiśniówka mining area (south-central Poland). This covered three acid pit bodies, historic tailings acid ponds, acid pools, and additionally two neighboring rivers. All these acid mine drainage (AMD) waters are characterized by the pH in the range of 1.7 (pools) to 3.5 (tailings ponds). The most interesting is the Podwiśniówka acid pit lake...

Epidemiological studies indicate that living in proximity to coal mines is correlated with numerous diseases including cancer, and that exposure to PM10 and PM2.5 components could be associated with this phenomenon. However, the understanding of the mechanisms by which PM exerts its adverse effects is still incomplete and comes mainly from studies in occupationally exposed populations. The aims...

Purpose. To develop a methodology for assessing the quality of drilling-and-blasting operations when setting side to final position. In this regard, it is necessary study nature deformations in near-side masses design open-pit contours and assess seismic impact blast waves accordance with damage near far zones from boundary, as well level generated vibrations. Methodology.A at limiting contour ...

BACKGROUND Tanzania has a young mining history with several operating open pit and underground mines. No prevalence studies of noise-induced hearing loss (NIHL) have been conducted among mine workers to provide an impetus for the development of comprehensive hearing protection programmes. AIMS To determine the prevalence of NIHL and associated factors among miners in a major gold mining compa...

determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. one of the important operational con...

Open pit mining of rock minerals and the affected areas requiring further development are a serious challenge for shaping positive image industry among public. The direction method post-mining land reclamation important this image, which should take into account various factors describing area, including social preferences. article presents an example solution – fuzzy system (FSDR) supports sel...

During early phases of open-pit mining production planning many parameters are uncertain, and since the mining operation is performed only once, any evaluations based only on on average outcomes neglects the very real chance of obtaining an outcome that is below average. Taking into account also that operation costs are considerable and the mining horizon usually extends over several decades it...
