- 26 - <br />• <br /> <br />• <br />rfined Land Reclamation Board. <br />7.4 CHEMICAL TESTING <br />We have carefully reviewed the results of chemical <br />testing of the roof and waste rock performed by CWI, and <br />the comments of MLR. We feel that additional testing of the <br />roof, floor and interburden material should be performed. <br />In order to meet the requirements of the MLR for proper <br />determination of the nature of the projected coal processing <br />waste, complete chemical and textural analyses will be per- <br />formed during Phase 2 of our work on the roof, interburden <br />and floor material. Two samples of each material will be <br />taken and subjected to testing. <br />To conform with the requirements of the MLR, the <br />samples should be selected from representative borings or <br />sampled directly in the mine so that the sampling locations <br />can be defined. <br />7.5 SOIL AND ROCK TESTING <br />As discussed in previous sections, samples will be <br />taken from all borings drilled at the site. Samples will be <br />shipped to the laboratory and a series of tests will be <br />performed. <br />In addition to testing of index properties of soils, <br />triaxial and direct shear testing of the fill material and <br />of representative samples of in situ soils will be performed. <br />Data on the shearing resistance obtained from these tests <br />c[aNVOao cowurn+c, wc. <br />
