2.05.3(6) SURFACE BLASTING PLAN <br />During preliminary excavations at the King II portal area, a hard sandstone <br />stratum was uncovered that may require surface blasting to break and loosen <br />in order to facilitate excavation of the portal bench. The surface blasting plan <br />is designed to address this stratum at the portal bench and any other areas at <br />the King II Mine facilities area. <br />National King Coal anticipates retention of a licensed Colorado blaster to <br />undertake surface blasting activities and will not store explosives on site <br />(except during the times the blaster is present and preparing the shot). <br />Types and Approximate Amounts of Explosives to be Used <br />Only one type of blasting operation is anticipated, the shooting of hard <br />sandstone that cannot be broken or removed by other feasible means. <br />The type of explosives to be used are anticipated to include ANFO, dynamite, <br />and detonation cord. The amount of explosive to be used is anticipated to be <br />more than five pounds per blast and less than 2000 pounds per blast. <br />Surface Blasting Records <br />A surface blasting record form will be completed and retained at the mine office <br />for at least three years after each surface blast at the mine. The form is <br />included in Appendix 11(2). <br />Blast Warning and Site Access Control <br />A blast warning will be employed prior to and after surface blasting at the <br />mine. The pre-blast warning will consist of an audible oscillating siren one- <br />minute long at one minute intervals for the three minutes prior to the blast. <br />The post-blast all cleaz signal will consist of five short air blasts of the siren ten <br />seconds apart, repeated three times. <br />Site access control will consist of personnel clearing the blast area of all non- <br />blast related personnel and barricading the blast area with heavy equipment at <br />all access points (roads and trails into to blast area). The barricades will be <br />maintained for fifteen minutes prior to the blast and until the last all-cleaz <br />signal has sounded. <br />Blast Monitoring, Pre-Blast Surveys <br />As there are no dwellings, public buildings, schools, church, or community or <br />institutional buildings within one half mile of any blasting area, nor is the <br />National King Coal LLC King II Mine <br />Section 2.05.3 <br />Page 7a Apri12007 <br />T~-iZ <br />
