Blasting Safety – Revisiting Site Security

(4.5 billion pounds) was used by the mining industry [USGS, 2004]. Blasting is a great tool in fragmenting and loosening rock and other materials for easier handling and removal by mining equipment. However, blasting creates serious concerns for the mine operators and miners in terms of Blasting Safety – Revisiting Site Security

created by blasting operations. Additional CH4 may come from the overburden, which is broken up during the mining process, and the underlying strata, which may be fractured and distressed due to the removal of the overburden. Emissions per ton of coal are generally much lower from surface mining than from underground mining.

How to leverage your bottom line with good drilling and

The above figures show to what extent the bottom line profit of a mining house can benefit from accurate drilling combined with the best initiation system. Good drilling and blasting practices are worth implementing. 90 MARCH/APRIL 2000 The Journal of The South African Institute of Mining and Metallurgy Table I Average Face Advance per Blast

H BLASTING IN SURFACE EXCAVATION Mining and

In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)

Demining Wikipedia

Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves. By contrast, the goal of humanitarian demining is to remove all of the landmines to a given depth and make the land safe for human use.

What Can Be Done to Prevent Mining Accidents?

People in charge of blasting operation attend specific training and are required to be licensed for the use of explosives and initiation systems. Most mining countries set up a specific refresher safety training for experienced blasters to integrate fastpaced changing legislation (especially after 9/11) and the new technological trends.

Blasting: Best Practices AggMan

Bench practices are the most readily observed of these items and are what most audits of drill and blast focus on. This auditing is essential but what is often missed in this process is the link between safe and effective bench practices and control of the blasts, as well as the effect on the economics of a blast, if not implemented well.

that are important to blasting operations. The purpose of drilling into rock is to provide a "blasthole" into which explosives can be loaded. Good drilling practices include carefully monitoring drillrig operating parameters, taking careful notes of the changes in geology during drilling, and effectively communiing to
