    INTRODUCTION SHOCK*STAR NON-ELECTRIC INITIATION SYSTEM DESIGNED AUSTIN DETONATOR S.R.O., CZECH REPUBLIC. THIS INITIATION SYSTEM INCREASES SAFETY AND ENSURES BETTER BLASTING RESULTS. THE SYSTEM WAS INTRODUCED TO THE MARKET IN 1993 AND SINCE THEN HAS SEEN THREE MAJOR MODIFICATIONS TO THE Surface CONNECTOR WHICH BROUGHT FURTHER RELIABILITY, PRECISION, AND SAFETY TO BLASTING IN FIELD.

  • Page 4: Components Of Non-Electric Initiation System And Their Function

    COMPONENTS OF NON-ELECTRIC INITIATION SYSTEM AND THEIR FUNCTION Austin Shock Tube and all Austin Detonator products using Austin Shock Tube can be initiated by regular electric, electronic or non-electric detonator, detonating cord, plain detonator, Shock*Star Bunch, Shock*Star Surface, proper blasting machine (from an open end of the Shock Tube only) and Rock*Star Starter.

  • Page 5: Operation Principle Of A Non-Electric System

    OPERATION PRINCIPLE OF A NON-ELECTRIC SYSTEM The basic principle of initiation in blasting pattern is transferring initiation from Surface Connector to a detonator in a hole and to another surface connector. The figure 2-1 shows properly timed blasting pattern - the holes are initiated well before the rock starts moving.

    Use double loops for longer primers (≥700 mm). (Fig. 4-7) Fig. 4-7 USE of Shock*Star MS DETONATORS IN SURFACE APPLICATION The explosive in the blast hole is usually initiated in-hole detonators Shock*Star MS. One detonator is located at the bottom (lower) part of the drill hole. The other detonator is positioned at the top (upper) part of the drill hole, under the stemming.

  • Page 14: Instruction For Use Of Shock*Star Surface

    NOTICE ON THE SAFETY OF SHOCK TUBE Snap & Shoot Effect  In the history of use of the non-electric (Shock Tube) initiation system, there occurred several instances of accidental tube initiation when the tube was pulled till its breakage. The instances were recorded during tubing production, detonator manufacture and also charging operations in the field.
  • Page 15 Fig. 4-10 Locking the tubes into connector CAUTION During connection make sure that the tubes are properly inserted into the connector block and that they are not crossed inside the connector block. Each side of the connector block can hold up to 4 tubes; the total capacity of the block is 8 tubes.
  • Page 16 CAUTION Connect, place the connector at the distance at least 60 cm from the next connector or in-hole detonator. (Fig. 4-13, 4-14) Fig. 4-13 Fig. 4-14 DISCONNECTING Hold the loop as when connecting and pull the tube out from the connector block. Fig.

  • Page 17: Added Delay Created By The Shock Tube

    ADDED DELAY CREATED BY THE Shock Tube As described Austin Shock Tube has velocity of detonation 2,000 m/s. This speed creates delay of 1 ms per every 2 m of Shock Tube. From this reason it is necessary to count with added delay by the Shock Tube and its variation based on place where connection to the Shock*Star Surface connector is been made.

    INSTRUCTION FOR USE OF Shock*Star DC Relay Steps to follow to make proper CONNECTION Fig. 4-20 Correct way to connect Shock*Star DC Relay NOTICE For easy connection it is important to have a clean cut of the detonating cord. Place the cord on a wooden plate and cut the cord at right angles using a sharp knife.

  • Page 20: Coupled Initiation Blasting Pattern

    Fig. 4-21 Austin Detonator, on the other hand, recommends designing the blasting pattern in such a way, that if in one element, the initiation is stopped, entire initiation process is stopped and only properly initiated holes blast. This method is shown in figure 4-22 and is considered by blasters as an important preventive measure which could be taken to avoid problems with removing misfires.

  • Page 21: The Bench Blasting Examples

    4.7.3 The bench blasting examples Three-row one-side-initiated bench blast All blast holes are charged with detonators of identical nominal delay time. Shock*Star Surface provides individual blast hole timing. The delay between holes in the rows is 17 ms, the delay between rows is 67 ms and 100 ms.
  • Page 22 Floor height leveling in one shot with bench blast Fig. 4-26 shows ideal approach toward connection of a hump blasting together with production bench blast. The approach should be that the small blast goes before the production blast and that the production blast is connected to the hump.

  • Page 23: Using Shock*Star In Underground Applications

    USING Shock*Star IN UNDERGROUND APPLICATIONS The advantage brought by non-electric initiation system Shock*Star can be conveniently used for tunneling and underground blasting as well. Shock*Star TS has been especially designed for these applications. Normally, the detonator is inserted into a booster or an explosive charge to form a primer for the hole.

  • Page 31: Package, Storage And Shelf Life

    PACKAGE, STORAGE AND SHELF LIFE PACKAGING Assembled non-electric detonators are packed into cardboard cartons. Inside the cartons the detonators are packed in vacuum-sealed plastic bags. The quantity per carton is determined by the Shock Tube length (see product information brochures for each separate product). The cartons are tested and certified and are in strict conformity with the International Agreement of Road, Train, Sea and Air Transport (ADR, RID, IMDG, IATA).

  • Page 32: Shelf Life And Storage Conditions

    SHELF LIFE AND STORAGE CONDITIONS a) For non-electric detonators packed in original unopened aluminum foil bags, the shelf life is 2 years, if stored in temperatures between -30 and +40°C. After opening the foil bag, it is recommended to use the detonators within 3 months. For non-electric detonators packed in original unopened plastic bags, the shelf life is 2 years if stored in temperatures between -30 and +40°C and relative humidity not exceeding 65%.
