Rak usne šupljine šesti je oblik karcinoma po učestalosti u svijetu (1). U Europi rak usne šupljine i rak ždrijela zajedno zauzimaju sedmo mjesto po pojavnosti (2, 3). U incidenciji tih bolesti postoje velike zemljopisne i regionalne varijacije te se bilježi porast stope incidencije osobito kod muškaraca (4 6). U Hrvatskoj je 2008. godine bilo 487 novooboljelih na 4 milijuna 437 tisuća i 460 st...

Building the knowledge culture is of increasing importance, not only because of its role in providing sound knowledge management and effective knowledge-based economic development, but also because of its support to environment protection, intercultural harmony and human well-being. This paper provides a review of the knowledge culture and its related issues, and introduces a development framew...

Abstract Sublevel shrinkage (SLSh) is an underground mining method similar to sublevel caving (SLC) but with continuous backfilling from the top. It features a top-down sequence production drifts orientated in longitudinal or transverse way orebody. Fan drilling and blasting done drifts, where ore then drawn. While drawing, backfill introduced at top flows down by gravity, which supports walls ...

The caving method and mining disturbance may cause geological issues. advance prediction of unfavorable bodies should be conducted to ensure product safety in the underground mine. In this study, we proposed OCTEM-PHA analysis process analyzed Tongkeng Mine Guangxi. Further, opposing-coil transient electromagnetic (OCTEM) detection on four lines T5-1 stope at mine level 386 by using portable re...

The mining of layered soft bauxite under coal seams (BCS) will cause serious underground goaf disasters and surface Bayer process red mud (BRM) pollution. In order to realize the safe efficient BCS, feasibility recycling BRM as a backfilling aggregate was explored. A series tests were conducted prevent pollution diversion from storage goafs, numerical simulation analysis carried out based on FL...

IOM predstavljaju jednu od tri najčešće lokalizacije svih bolničkih infekcija (BI). U SAD one čine 14–16% BI . Kod operisanih bolesnika u ovoj zemlji to su najčešće od svih BI i zastupljene su sa 38% . Stopa incidencije IOM u drugim razvijenim zemljama se kreće od 2,2 5 do 4% , dok u nerazvijenim zemljama, odnosno zemljama u kojima sistem nadzora nad BI kao i njihova prevencija i kontrola nisu ...

SYNOPSIS This paper describes some important aspects associated with historical underground measurements in South African gold and coal mines. Deformation were used to confirm the use of elastic theory simulate rock mass behaviour Witwatersrand mines 1960s. Although a prominent time-dependent component stope closure was measured as early 1930s, it ignored owing benefit adopting theory. Neglecti...

On the basis of a conceptual model for an Excavation based Enhanced Geothermal System (EGS-E), which proposed to extract heat from Hot Dry Rock at depth through dominantly adopting shaft, roadways, and caved rock failure techniques but not depending on either wellbore drilling or fracturing stimulation, novel extensive version extraction is in this paper. Considering its mechanical stability is...

Significant economic and environmental advantages can be expected using cemented paste, especially in mining as a backfill for room-and-pillar excavated method. But, it is necessary to investigate the behaviour of paste within mine stope. In this paper will presented results stress-strain analysis stope stability excavation method, before after backfilling with on model developed plane (2D) cor...
