Yima Coal Corporation is considering to adopt highwall mining method withauger machine to recover coal from north surface pit that has reached final highwall position. Themajor geomechanical issues associated with auger mining are highwall and pillar stability. Based onthe field investigation and laboratory test results of mechanical parameters, numerical modeling iscarried out to assess the stability of highwall and pillar. Field measurements of highwalldeformation have been used to validate and ensure the confidence for the development of realisticmodels. The results of numerical modeling show that the mining method is feasible for mining theseam of 10 m thickness in north surface coal mine.

A semi-continuous technology combines the merits of discontinuous and continuous technologies. Compared with the discontinuous technology, the semi-continuous technology can be used to decrease haulage costs in mines be- cause of the use of a belt conveyor instead of trucks. The method may improve efficiency by using shovels instead of BWE. This paper discusses the removal distance of a crushing station based on the Buzhaoba surface mine.

The three-dimensional （3D） deformation effect of the slope engineering under the step-by-step excavation for the Antaibao surface mine was analyzed using the FLAC^3D technique. An optimal excavated scheme with a relatively steeper slope angle of 47° instead of 30° was successfully implemented at the west wall in the geological section 73200 of the mine area, where the 3D effect of the nonlinear large deformation of the slope was taken into account. Based on the above research conclusion, put forward the countermeasures of shortening mining length, excavating by different regions, timely foot backfilling to protect the excavated slope, and monitoring and feedback adjustment by studying the nonlinear effect. The results show that these countermeasures are effective in controlling maximum deformation and increasing the stability of the slope.

It is stipulated in the China national document, named'The Economical Appraisal Methods for Construction Projects' that dynamic analysis should dominate the project economical appraisal methods. This paper has set up a dynamic investment forecast model for Yuanbaoshan surface Coal mine. Based on this model, the investment reliability using simulation and analytic methods has been analysed, and the probability that the designed internal rate of return can reach 8.4%, from economic points of view, have been also studied.

The Modified Universal Soil Loss Equation (MUSLE) is often used for sediment-yield estimations insurface mines for design and impact evaluations. However, it is not known if the widely-used runoff-energy factor of MUSLE is appropriate, or if its parameters are the same for surface mines as foragricultural watersheds from which MUSLE was developed. Suspended-sediment data from threeexperimental watersheds in Ohio (approximately 1O - 2O ha), subjected to near complete distUrbance dueto mining and reclamation, were used to investigate five altemate runoffenergy factors in the MUSLEsediment-yield model for use in surface mines. The evaluation led to the selection of the generalizedmodel form, a (runoff volume X peak flow rate)b, as the best choice among models *** b was greater than the widely-used value of 0.56, ranging from 0.68 to 1. 10. Parameter b wasdependent on whether mining-or reclamation-related watershed activities were predominam. Theoriginal Williams (1975) model fit the data least well of the five energy factors studied.
