The Technique Measure of Control Dynamite for the Blast Area of Careful Homework in the JDC

摘要

To ensure that the mineral mountain production safety and side ascent lasts long a stability, for raising opening mine stability of having been formative permanent side slopes and side of blast quality, lowering production blasting to vibrate harmful effect and decrease dangerous pumice for the side of opening mine. This text mostly describe the application that blows up technique measure, and passes to prepare a crack, buffer blasting and the typical model design of software etc, and carefully design to the blast area of the JDC, especially practiced mine for minerals a partial the careful blast area, blow up effect to obviously get an improvement Not only effectively protected deeply cave strip mine permanent side slopes having been formative mine the whole stability in the term in the mineral mountain, and also protect to flow through the Dong Chuan river of the neighborhood of mineral body to change river hole and be located in to adopt the 1056 m in the field to pour fixed pump station, nearby villager's common people's houses of segment and construct the safety of thing.
