2.0 Design <br />This section discusses the highlights of the design. <br /> <br /> <br />Detailed calculations, drawings, specifications, and test results appear in the <br />tabbed sections which follow. <br />2.1 Location <br />The bulkhead locations are constrained by the fact that stopes are farther inby, <br />rendering bulkheading any farther in impracticable. (See Drawing Sheet 2). <br />The Steve location at approximately 265 feet in from the portal (to the inby side <br />of the bulkhead) was selected to avoid the timbered area just outby the vein / <br />stope intersection, and also to incorporate a visibly iron stained seepage point <br />source on the south rib within the bulkhead. Additionally, this location had <br />favorable geometry, with a natural "keyway" with an enlarged area bounded by <br />smaller cross sections inby and outby. <br />-~- <br />., ~t <br />.~ <br />~ ~. ~+ <br />~~ K ~l~{ <br />`c . ~~ <br /> <br /> <br />Figure 1: Steve adit bulkhead location, showing seep on rib. <br />
