In most surface mining, overburden removal operations require haulage over short distances. This is a key operation for companies using the strip mining method, because of the large amounts of waste to be removed. Other methods and operations also adopt this type of transport, using dozers, excavators, front-end loaders and haul trucks. A comparison of different haulage options for short distances with respect to energy efficiency in open-pit mining is needed, but only a limited number of recent studies have considered energy efficiency as a key variable in mining projects. This study therefore seeks to develop a mine design that is able to achieve greater energy efficiency without affecting the performance of mining operations. For this purpose, simulation tools and comparative analysis among several equipment options are used. After implementation, a 14% reduction in specific fuel consumption and a 16% increase in productivity are found.

With decades of development and exploitation of coal resources, the first batch of coal-based cities in China are faced with the challenge of economic shrinkage and environment deterioration due to the rapid resource exhaustion and single industrial structure. Nowadays, as a policy instrument for sustainable development, a nationwide circular economy mode has been implemented during the design and planning of new coal mines to address the challenges arising from economic depression, energy shortage and environmental pollution. It should be mentioned that several national coal bases and most of constructing and planning coal mines are located in the underdeveloped areas in the Midwest of China which means that the distance between supply source for energy resources and the demand market is significantly increased. Moreover, the ecoenvironment vulnerability in these rural areas should be taken into serious consideration. Therefore, after comparison and analysis with several successful coals based and diversified circular industry chains, this paper presents a case study on the circular economy park (CEP) in the northwest of Shanxi Province. Through discussion and evaluation of '1+3' mode in the CEP, this paper aims to enhance the understanding of coal mine sustainable development and shed light on the relationship between resources exploitation and local economic development.

“…Some studies adopt a perspective of corporate social responsibility by investigating the social and environmental reporting trends of leading mining firms (Bond, 2014;Dong et al, 2014;Onn and Woodley, 2014). A series of management tools has been developed to assist mining firms in improving sustainability performance (Levesque et al, 2014;MacDonald, 2006). Some studies analyze the regulatory and institutional aspects of small-scale coal mines development in China and conclude that China needs to establish a stable, transparent and inclusive legal and fiscal framework to create a sound environment for the operations of small coal mines (Shi 2013;Andrews-Speed et al 2003;Andrews-Speed et al, 2005;Shen and Gunson, 2006;Shen et al 2009).…”
