Market research on mechanical stemming device: Part 3. [USA: 1984; by state and explosive type]
The stemming device has application for any explosive loaded blast hole. The primary market areas are coal mining, hard rock mining, and construction. An average of 7.6 million boreholes are drilled annually with 41/percent/ in coal mining, 23/percent/ in quarry operations, 21/percent/ in construction, and 15/percent/ in metal mining. There are no other stemming devices on the market. The current practice is to drill the hole, fill the hole with explosives, and stem the explosives by packing the rock cuttings on top of the explosive column. This conventional stemming material would also be used in conjunction with the stemming device. Thus, the stemming device is competing with a practice that has no material cost, i.e., the waste material from the drilling process. Therefore, the cost of the stemming device must be offset by an overall reduction in blasting cost through reduction in the number of holes drilled, related reduction in drilling labor costs, and improved fragmentation (reduction in secondary and tertiary crushing costs). In addition, the stemming device reduces the blasting noise which is a consideration in populated areas. The customer must be shown the net savings from using the stemming device. The stemming device is easily copied and manufactured and thus is expected to attract competition if it is successful. The strategy will be to establish the stemming device as the dominant force in the market supported by expertise in blasting applications, while reducing device manufacturing/material costs to the minimum.
