General Blasting Plan <br />This plan is intended to present guidance, control, data and information that <br />will serve the mines of Summit brick & Tile Co. Shooting at these sites should <br />follow these procedures, limiting charge size, number of shot holes, and the <br />recommended controls. The Fox mine is the site of the thickest overburden <br />and thus the hardest shooting. This plan demonstrates that all other mines <br />have much less blasting effects, and as a result, less affects. The schedule for <br />blasting at these sites is highly variable, based upon market conditions and <br />inventories. Shooting may take place bi-weekly, monthly, or on an as needed <br />basis. Below is a general list of controls and procedures which Summit Brick's <br />blasting contractor will follow. <br />1. A licensed blasting contractor, who is qualified and <br />maintains the expertise in all phases of the work, will <br />conduct blasting. <br />2. The blasting contractor will be entirely responsible for <br />supplying, storage, and handling of all blasting <br />materials, in addition, he will maintain the security, <br />traffic control if bL~.sting within 1000 ft. of any public <br />road as prescribed within this document. <br />3. There will be no shooting within 50 feet of a buried <br />phone line, or within 50 ft. of unimproved roads, and <br />750 &. of a paved state road. <br />4. Size and charge set for each shoot will comply with the <br />"8- millisecond role" or other timing delay which <br />meets standards, and be 16 Ib. or less. <br />5. There may be small limited amounts of blasting <br />materials, which are stored on siteq however, these will <br />be stored in approved powder magazine storage units. <br />6. All shot holes will be stemmed (covered with a <br />minimum of 2 ft. of dirt on holes less than 15 feet deep, <br />and 3 ft, of dirt on holes, which are greater than 15 feet <br />deep, prior to any shot being set off. <br />3 <br />
