“…The former methods main contains isoline method, profiling method, arithmetic mean method, geologic block method, triangle method, polygonal method, and so on. The later kinds of approaches developed rapidly, and many methods and models have been brought forward, such as isofactorial binormal distribution model (Guertin, 1987), the Jackknife method (Varljen et al, 1998), density spectrum method (Yao, 1998), the geo-statistic method (Hou and Huang, 2001), the optimization algorithms method (Bastante et al, 2003), the box alternation coordinate system and multiple reserve calculation integration method (Cao and Chen, 2003), the grid subdivision and integral method (Wu et al, 2007), and so on. In China, traditional geometry-based methods are most commonly used because these methods are suitable for the actual characteristics in Chinese mining areas (Zhao et al, 2010;Zhang et al, 2011).…”

This study divided the oil shale segments and the quality grades; tested the oil content of oil shale samples in different segments; found out the distribution characteristics of the ore bodies in each segment; identified the ore-bearing properties of oil shale ore bodies; summarized the method, the range, and the parameter determination of resource estimation; and the divisional principle of resource blocks. Then the separate-level profiling method was chosen to delineate the oil shale ore bodies over and under the ground, and the profile lines, the bottom contour lines (horizontal lines), the outcrop lines, the synclinal axis, and the boundary line of the mining area were used to constrain the blocks. Finally, the mineable oil shale amount in the study area was calculated. The results show that the amount of low-quality, medium-quality, and high-quality oil shales are 3,482, 2,598, and 1,348 million tons, respectively.
