designs relative to neighbouring blasts and the total mine landscape. The system overlays related mine information and previous blasting outcomes, such as coal loss, to provide rapid and improved insights on previous blasts and assists in determining required changes for improvement in future blasts. Controlled energy delivered at the right time Energy control, along with movement of the waste

Cast Blast Design - MiningInfo - Google Sites

Cast blasting is a type of blast design which utilizes the surplus explosive energy to move overburden material across the pit. It is most frequently employed in coal mines to remove overburden from above the coal seam. This is achieved by arranging pits in long and narrow configurations that facilitate the movement of the blasted rock into the previously mined pit. This technique allows

Title Design blasting layouts and carry out shotfiring in

01.09.1987· BLASTING IN SURFACE COAL MINES Blasting overburden and coal in open pit mines is still considered to be an art. Even though much research has been done in areas related to surface mine blast design and anal- ysis, very little of this research seems to have been applied in blasting practice. Selection of optimum burden, or the powder factor, is still a matter of experience. Very often

Blasting Design of 1185m Level Bench of

To guarantee production safety and to improve the economic benefit of Heidaigou open-pit coal mine,the blasting design of level 1185 was optimized according to the specific condition and blasting requirement,and suitable blasting method was applied in main stope.According to the characteristics of covering rock on the coal seam,the high bench cast blasting method with pouring pile by using

BLAST VIBRATION STUDIES IN SURFACE MINES

BLAST VIBRATION STUDY AT OPEN CAST COAL MINE all the ill effects, ground vibration is major concern to the planners, designers and environmentalists. A number of researchers have suggested various methods to minimize the ground vibration level during the blasting. Ground vibration is directly related to the quantity of explosive used and distance between blast face to monitoring point as

Blasting pattern design - 1 - Underground

It is desirable that blasting pattern is simple in order to be easily drilled at site. Therefore, it is best practice to align boreholes in rows or to follow alignment as much as possible. After design it is necessary to determine basic blasting parameters as follows.

A novel powder factor based bench blast design method for

has yet to create a blast design method specifically tailored for large surface coal mine bench blasting. This research examines the typical scale of bench blasting at large surface coal mines, develops a new method of design tailored for these operations, and tests the new method against two widely accepted traditional blast design methods. Novel contributions of the research include a new

Citizen's Guide to Coal Mine Blasting in Indiana

Cast blasting is a type of blast design that uses the explosive energy to move overburden material across the pit. This technique allows approximately 25% to 50% of the rock to be moved without the use of mine equipment. This is a major cost savings to the mine. Although cast blasting requires more pounds of explosive for each cubic yard of rock . The. not. Citizen's Guide to Coal Mine

Blasting in Underground Coal Mines - Mining Science and

Blasting in Coal Mines •Modern mechanised coal mines use machines and longwall mining methods to cut solid coal and convey the broken coal out of underground workings. •Continuous mining equipment has escalated coal production and introduced more effective and efficient coal handling facilities.

H BLASTING IN SURFACE EXCAVATION - Mining and Blasting

Secondary blasting can be done by pop shooting (blockholing) and plaster shooting (mudcapping). Shaped charges are sometime used in secondary blasting, but this is much more expensive. Cast Blasting When overburden is removed from a coal or mineral deposit it is generally cast to a waste dump by draglines, or removed by loaders and trucks.
