Can also say that the [is based, external cause is the condition. Down the slope with almost all the (artificial slopes and natural slopes) are the same inside and outside Quebec under the action of the body so the title against calculated by c, the value is included under certain conditions, both inside and outside [q means the demolition of the integrated elements. . 2 R landslide-inch scale test of the body is much the dog, which includes geological factors} chiseled body is more than Bin Pan 7. 4.3 i shake a specific anti-body computed from c, the value of friends to be addressed for dredging or hug; on the condition of the slope close to dinner closer to the international health segment. Mr vain, according to more than 4.4 body operator H to a tough summer for the sliding mass index where the Bianpo section, is statistically and relatively accurate. Here inverse landslide l c, the value of calculation errors. V an absolute error of ten 6】 747f. 7C-7】 eleven 4tV2 = lO8lf +69.8 C relative error of a 600-0 Vt / Gsin ~ 4/47l = 0.008-0.8V2/Gsin ~ = o/6O0 = 0 cut the average relative error is 0. 4 above the allowable total error range. 5 Conclusion elongation in slope did not withdraw the article reports, in order to complete the Waitoushan Iron mining in the deep slope design, we work through this, and seek the c, value, and this applied to slope design. Make do with the post-test report slope control, we selected the value of slope angle and the report recommends the basic urge Taiwan, achieved satisfactory results expected. Therefore I believe that in the production of ore mining at lI】 i curtain towel slope design, if there is no slope studies, using the above principles and methods}, on the slopes of thirty boats have been exposed to the body, the research analysis, obtained inverse 0 , the value of design as an important basis for the slope is very practical. The reported instances of this, expect to design distribution on the slope of the benefit.
