Simplification of Complex Wiring Circuitry

Large production blasts involving many series in parallel have long been a source of complication. When speed and accuracy are most necessary in blast preparation an efficient and precise method of wiring is required. After loading a large number of holes and being pressured for time, due to lack of daylight, equipment shutdown, etc., an effective hook-up plan can eliminate many last minute problems. It is the intention of this paper to offer a simplified wiring proceedure which when employed can save precious time and encourage efficient and economical utilization of blasting personnel and material.
