Strip Coal Pillar Design Based on Estimated Surface Subsidence in Eastern China

Pillar design based on estimated surface (PDBES) is and its application in Daizhuang Coal Mine in eastern China is discussed. The purpose of strip coal pillar design is to use modern scientific and engineering practices to develop a safe underground mine in which the ground surface movement and deformation will be controlled to protect the surface buildings. This pillar design method is based on pre-mining estimations of surface subsidence. Surface subsidence is the main cause of potential damage to surface structures and must be estimated before coal mining.

Establishment and practice of higher educating system of Outstanding Mining engineer

Mining industry plays an important role in Chinese National Economy with more than 10 million persons serving for it, yet the quality and capacity of Chinese mining engineers has lagged far behind developed countries. In this paper based on “Plan for Educating and Training Outstanding Engineer”, according to the mining industry status and trend, the Plan for Educating and Training Outstanding Mining Engineer (PETOME) is put forward, which consists of educating objectives, educating standards, the educating plan of higher school and the enterprise plan. At the same time some questions and solutions in the practice of PETOME is claimed. Good results are achieved after PETOME practice in Shandong University of Science and Technology.
