Construction of intelligent coal mine knowledge map. Through the establishment of information entities, the mapping from the physical space to the digital space is realized. This mapping includes not only physical entities (, coal mining machines, hydraulic supports, and tunneling machines), but also time entities (, roof pressure, gas overruns, equipment failures) and functional ...

This paper describes an autonomous loading system for loadhauldump (LHD) machines used in underground mining. The loading of fragmented rocks from draw points is a complex task due to many factors including: bucketrock interaction forces that are difficult to model, humidity that increases cohesion forces, and the possible presence of boulders. The proposed system is designed to integrate ...

Coal is the major source of power in India and world over. Coal mining is an essential industry which has a major role in the economic development of the country. Most major mining activities contribute directly or indirectly to air pollution. Coal dust is a major air pollutant which affects the personal working in the mines and also people residing in villages near the mines. Air pollution ...

This study established a truck dispatching model adopting 01 decision variables to rationally allocate truck transportation in openpit mines, maximize the total loading and unloading volume of trucks, and solve the problem of the inability of the truck dispatching model to guide production in openpit mines because of nonspecific results. The model considers loading and unloading logical ...

Automatic truck loading and unloading systems have become the ideal solution for improving agility and safety during the goods receipt and dispatch process at the warehouse docks.. The loading docks are a vital part of any distribution more docks an installation has, the greater the goods flows or, in other words, the number of trucks that enter and leave the warehouse.

Transport activities in openpit mines contribute to a large portion of total energy consumption. Most truck scheduling studies still take a traditional approach to autonomous mining trucks, which does not fully exploit the strengths of the autonomous trucks that can perform more accurate speed control compared to conventional manned trucks. In this paper, a mixedinteger programming model is ...
