Abstract
AN INTEGRATED DRILL-LOAD-SHOT (IDLS) SYSTEM WILL BE DEVELOPED TO OVERCOME THE CURRENT DISADVANTAGES AND REALIZE THE POTENTIAL OF EXPLOSIVE EXCAVATION SYSTEMS. THE IDLS SYSTEM IS TEAMED WITH A UNIQUE SPIRAL DRILL AND BLAST CONCEPT, THE COMBINATION OF WHICH PERMITS NEARLY CONTINUOUS, RATHER THAN CYCLIC OPERATION. THIS CONCEPT PROVIDES A SIMPLE, REPETITIVE BLAST GEOMETRY, EFFICIENT BLASTING TO A FREE SURFACE, AND MINIMIZES SHIELDING REQUIREMENTS. IT PROVIDES OPERATING FLEXIBILITY RANGING FROM CONVENTIONAL BLAST STRENGTH WHERE GROUND CONDITIONS PERMIT, TO LIGHT BLASTING WHERE POOR GROUND CONDITIONS REQUIRE. THE SYSTEM SHOULD REQUIRE AN ORDER OF MAGNITUDE LESS ENERGY THAN A CONVENTIONAL TUNNEL BORING MACHINE. OBJECTIVES OF PHASE I ARE: 1) DEMONSTRATION OF THE ONLY REMAINING (UNPROVEN) CRITICAL SUBSYSTEM OF THE IDLS CONCEPT; AND 2) PRESENTATION OF A PRELIMINARY OVERALL SYSTEM DESIGN CONCEPT. DELIVERED AT THE END OF PHASE I WILL BE: 1) REPORT ON ALL WORK; 2) SYSTEM PRELIMINARY DESIGN; 3) PHASE II RESEARCH PLAN AND COST ESTIMATE; AND 4) IDLS PROTOTYPE HARDWARE COMPONENTS.
