They are also the main criteria for the selection of face equipment, mining parameters and support parameters.
After the first-mined seam and adjacent seam are determined, the equivalent relative interlayer spacing (Liu et al. 2010b) can be calculated according to the occurrence of the coal strata, mining parameters for the working face, and interlayer lithology coefficient.
In this paper, two mining parameters for the characterisation of methane emission, the methane emission rate (volume of methane emitted per ton of excavated rock) and average methane flow rate (volume of methane emitted per day), are introduced.
To investigate the relationship between the number of putative SNPs and SNP mining parameters, SNPs were mined under different parameter settings regarding the minimal available sequence information flanking the target SNP (1, 2, 3, 4, 6 or 12 bases), and the minimal interval of flanking sequence that must be devoid of additional SNPs (1, 2, 3, 4, 6 or 12 bases).
SNP mining was performed by varying these two parameters in all 36 (6 times 6) possible combinations, while keeping the other SNP mining parameters, including minimal representation of both alleles at least twice, homopolymer settings and segregation according to sample origin constant.
On the basis of these investigations, empirical formulations are attempted among the relevant geo-mining parameters for the design of a RBBLS.
Based on the long-term monitored data for Zhuji coal mine, the parameter inversion of the two different sections of the piebald mudstone has been conducted with the nonlinear least square method.
In inter-sentential language pattern mining, two parameters may affect the quantity and quality of the discovered patterns: the size of training data and threshold value of confidence (Eq. (2)).
With regard to the immense importance of cut-off grade in designing and planning open pit mines, optimizing this parameter has considerable effects in mining economic.
Pairs trading is inherently built around models that support data mining and dynamic parameter estimation scheme.
