Chapter 8 BLAST DESIGN - NPS

The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production ...

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

We understand that emergency response requirements differ greatly between sites, depending on their processing conditions, the location of personnel and dangerous goods inventory.


One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas).

Mining - OSRS Wiki

Mining is a skill that allows players to obtain ores and gems from rocks. The higher a player's Mining level is the more likely they are to successfully extract ore. With ores, a player can then either smelt bars and make equipment using the Smithing skill or sell them for profit. Mining is one of the most popular skills in RuneScape as many players try to earn a profit from the skill.


Nitric oxide (NO) and nitrogen dioxide (NO 2) are produced by large surface blasts in which the explosive does not detonate properly. NO released by the detonation oxidizes to NO 2 as the fumes mix with the atmosphere. Excessive NO 2 production is apparent as an orange cloud that forms above the blasting site. NO 2 is extremely toxic.


Mining Techniques of the Sierra Nevada and Gold Country by Snowy Range Reflections staff ... The first crushing equipment was the Mexican arrastra, a device that ground the ore between two stone slabs rotated by a mule or humans. The most effective and productive crusher was the vertical stamp mill. The hammers of these big stamps were lifted ...

Mining - The RuneScape Wiki

Mining is a gathering skill that allows players to extract ores, gems, rune essence, geodes, and other resources from rocks throughout RuneScape. Mined ores can be smelted at a furnace, turning them into bars that can be made into metal objects using the Smithing skill, Construction skill, or Crafting skill. On the World map, mines and mining sites are identified with a lump of ore (), and ...

Demining - Wikipedia

List of mining equipment: Mining is the extraction of valuable minerals or other geological materials from the land of a deposit. For this extraction to be done efficiently, we need machinery specialized in mining. These mining equipment have reinforced chassis and more powerful engines so that they can transport all the material.
