Ore body Borska Reka in Jama Bor underground mine has been a challenge for experts in underground mining for many years. Specific properties of this ore body, such as great depth, huge ore reserves, low ore grades, infrastructure at ground surface above the deposit, along with variation of metal prices, disable application of traditional and previously applied mining methods. This paper presents results of researches related to design of new mining method, from the group of induced caving methods, and possibilities for application of such method in ore body Borska Reka, along with calculation of main method parameters.

Mining is often the subject of a study of safety and health at work as one part of industry that carries the greatest risk of injury. The most of these analyses are directed on studying the method of injuries of workers and procedures that can prevent injury. Financial expenditures resulting from injuries of workers in Bogovina coalmine which occurred in 2016 are analyzed in this paper. Injury costs were processed based on the available data: compensations of the insurance companies to the injured workers, gross salaries of injured workers and similar. Within these data, the "cost of one work day lost" (COWDL) is defined. Comparison of the COWDL, based on qualification structure of the injured worker and the severity of the injuries, was performed. Also, an impact analysis of expenditures related to indemnity related to injuries at work to mine operational costs were carried out.

The risk of an injury at work, occupational disease or damage to the health of employees due to danger is, lately, the common subject of numerous studies.

Izvod Metoda podetažnog zarušavanja, koja se često naziva i «švedskom varijantom UVODRazvoj metode podetažnog zarušavanja u najvećoj meri je posledica odgovarajućeg razvoja rudarske opreme, pre svega mašina za bušenje i miniranje i mašina za utovar i transport rude. Kada se hronološki sagledava razvoj ovih mašina, naročito u drugoj polovini prošlog veka, jasno se uočava velika zavisnost ovih okolnosti. Poznati svetski proizvodjači rudarske opreme permanentno su usavršavali, pre svega mašine za bušenje, namenjene primeni metoda podetažnog zarušavanja, u okviru toga prevashodno za varijantu ove metode koja se naziva «švedskom varijantom (slika 1, [1]) Sl. 1. Švedska varijanta podetažnog zarušavanja sa romboidalnim oblikom rudnog bloka u kome se ruda obara dubokim minskim bušotina sa specifičnim rasporedom
