RECE�V E� <br /> Martin Marietta Red Canyon Quarry <br /> JUN 3 0 nis Blasting Procedures <br /> pIVIS10N OF RECI_�ftocument shall be reviewed and. and updated as needed, on an annual basis. <br /> MINING AND SAFETY <br /> 1. Blast Design <br /> • Before a new blast pattern is designed, results from the previous blast, including seismic outcomes, will be <br /> reviewed by quarry management and the blasting contractor. <br /> • Safety and environmental considerations, including nearby neighbors,will be discussed prior to blast layout. <br /> • No holes will be drilled without discussion with the blasting contractor, and quarry management, to <br /> determine the location and design that is best fit for the intended blast outcome, and the capabilities of the <br /> blasting contractor's crew and equipment. <br /> • At a minimum, all holes along an open face will be placed by the blasting contractor after measurement of <br /> the face profiles, or with the assistance of setbacks. <br /> • Any changes in blast design parameters (burden, spacing, borehole diameter, etc) will be communicated <br /> and documented via the drill log and/or blast layout diagram ("dot sheet"). <br /> 2. Blast Scheduling and Notification <br /> • All blasting will be conducted on weekdays, and between the hours of 8am and 3pm. <br /> • Blasts will be scheduled with the blasting contractor at least 72 hours in advance. <br /> Planned Blast Date: /,•-i-J r, Planned Blast Time: c�- <br /> • The following persons/entities will be notified at least 72 hours in advance. <br /> Tim Cazier, Colorado Division of Reclamation, Mining & Safety: 303.866.3567, ext. 8169 <br /> Ken Bishop, adjoining property owner: ken kidlynx.com <br /> • If a scheduled blast must be postponed due to weather or other complications, the above persons must be <br /> notified as soon as possible, and updated with the revised blast schedule. <br /> 3. Blast Reporting and Recordkeeping <br /> • A blast report will be completed by the certified Blaster In Charge after each blast, and will include the <br /> following information, at a minimum. <br /> Blast date, time, and location, including GPS coordinates of the blast. <br /> Weather conditions and wind direction. <br /> Blast hole diameter, depth, explosives and inert(stemming) load, and quantity. <br /> Overall blast geometry, including hole burden and spacing, tonnage, and a blast diagram. <br /> Overall explosives consumption, including detonators and packaged explosives product. <br /> �w Seismic data recorded from at least one critical location, such as the nearest non-quarry-owned <br /> inhabited structure. <br /> After blast loading is complete, and prior to initiation, explosives inventories will be counted and <br /> compared to load records to ensure no explosives were left on-bench. Prior to departure, the <br /> blasting contractor will provide quarry management with a record of all explosives consumed onsite. <br />
