SITE LOCATIONS & GEOLOGY 2. The Patton Clay Mine: (Permit # M-1998-067) Map 5. shows the general location of the Patton Clay Mine, accessable from US Rte. 50 +/- 2 miles east of Canon City, Co., via Cty. Rd. 69 where the geology consists of the strata and clays of the Glen Eyrie Shale member of the Fountain Formation. Further, the map shows streams, roads, utilities, wells, all dwellings with in 3000 ft., and other structures. There are no dwellings and wells exist within 3000ft. of the proposed blasting. There is extensive published geological work has mapped the Fountain Formation with the associated clays and shales throughout Fremont County. It is the Eyrie shale member who's stratigraphic position is several thousand ft. below the Dakota Group, and contains shales and clays which have brick making properties. Site specific geology indicates that strata of the Glen Eyrie striking N 30~ W and dipping to the north-east, out-crop 220 ft. above an alluvial valley floor, where Wilson Creek flows. Lonnie Loader Construction of Penrose, Colorado normally conducts blasting. Overburden consists of thin poorly cemented sandstone and shales about 5 to 15 feet thick. Due to the nature of the softness of the clays below the blasting level, a portion of the blast impulse is absorbed on site. Blast holes are usually 3.5 in diameter with an average depth of 8 ft on 8 foot centers. All holes are stemmed with 2 feet of dirt, thus powder thickness is usually less than 5 feet. An Ez-Det. delay system is incorporated with 25/350 milliseconds is used combining 2 holes. Mr. Loader is always striving to maintain his high level of expertise, by staying abreast of timely changes with in the blasting industry, where new techniques and devices are introduced as proven to aid in blasting to eliminate vibration and noise.
