矿井通风系统评价指标的探讨

以往我们常用“等积孔”和“有效风量率”来评价矿井通风系统。我国江南地区不少煤矿井型小、产量低、地压大、构造复杂，有些矿井通风系统较复杂，单凭以上两个单项指标，难以真实地反映矿井整个通风系统的好坏程度。等积孔的量值，仅仅反映了矿井通风的难易程度。等积孔大的矿井，通风容易，但并不能说明矿井通风系统好，有效风量率高的矿井也不一定是矿井通风系统好的矿井，须区分矿井通风系统好坏程度与难易程度两个概念。

国际铀资源分类方法综述

系统地介绍了世界上2个主要铀资源分类系统。这2个主要的资源分类系统是在不同的理念指导下制定的,两者的制定和完善过程完全不同,所依据的准则、使用的术语和定义有很大的差异,但都是基于2个要素,即地质可靠程度和与生产成本有关的经济性。各产铀国所使用的分类方法或多或少都与这2个系统有着密切的关系,只是在具体的操作或计算方法上因各国的政治经济体制和习惯不同而有所差异。随着世界经济的一体化,这2个分类系统有趋于一致的可能。     

Mining fleet management systems: a review of models and algorithms

The objective of this paper is to review and document the mine fleet management systems’ models and algorithms. The purpose is to understand the algorithms behind the fleet management systems and the proposed academic solutions in this area to identify any gaps in the current literature and to open up opportunities to establish research questions that need to be addressed in an integrated simulation and optimisation operational planning research framework. In this paper, we review industrial fleet management systems and the main academic algorithms behind such systems. The fleet management systems are divided into three subsequently related problems to review: shortest path, production optimisation and real-time dispatching. Finally, the limitations of current algorithms for fleet management systems are documented in terms of mining practice feasibility and optimality of the solution on large-scale problems. The results of this literature review enable us to evaluate the logical links between major components of an integrated simulation and optimisation operational planning framework with current theory of fleet management systems.

Expert systems: Opportunities in the minerals industry

Since the inception of expert systems in the early 1980's their application has spread to a wide variety of industries. There are now thousands of successful expert system applications providing real benefit.The medical profession was the first to utilize expert systems technology through the now classic MYCIN system. During these formative years the minerals industry was quick to identify the potential of these systems. PROSPECTOR for ore body identification was the first expert system associated with the minerals industry.Since the early years the minerals industry has embraced the new technology with an unexpected fervour. At present expert systems can be found in most areas of the mineral processing, extractive metallurgy and mining industries. Many applications are off-line or stand alone in nature, although increasingly on-line and real-time systems are appearing.The aim of this paper is to review the current status of expert systems, both within the minerals industry and in other spheres of industry. Expert systems associated with applications as diverse as the nuclear power industry and brewing are examined.Through this review future developments and applications within the minerals industry are suggested and explored.

Detecting change in dynamic process systems with immunocomputing

The natural immune system is an adaptive distributed pattern recognition system with several functional components designed for recognition, memory acquisition, diversity and self-regulation. In artificial immune systems, some of these characteristics are exploited in order to design computational systems capable of detecting novel patterns or the anomalous behaviour of a system in some sense. Despite their obvious promise in the application of fault diagnostic systems in process engineering, their potential remains largely unexplored in this regard. In this paper, the application of real-valued negative selection algorithms to simulated and real-world systems is considered. These algorithms deal with the self–nonself discrimination problem in immunocomputing, where normal process behaviour is coded as the self and any deviations from normal behaviour is encoded as nonself. The case studies have indicated that immunocomputing based on negative selection can provide competitive options for fault diagnosis in nonlinear process systems, but further work is required on large systems characterized by many variables.     

Design of haul road lighting system. Part III: application

The design of haul road illumination systems based on a scientific approach is very important. Improperly planned lighting systems may provide unsatisfactory illumination and may also incur higher costs. This paper describes illumination systems designed for two haul roads using the computer programs developed in earlier stages of this work. System performances and cost are compared with the existing illumination system. Designs based on the developed programs show total potential cost savings of approximately 26% and 48% for the two systems.
