Mining machinery will move toward new development in the future

The frontier of modern science and technology has remarkable time domain, domain and dynamic characteristics. The cross-convergence of different sciences will generate new scientific focus. Economic development and social improvement will bring new expectations to mining machinery. The development of mining machinery is closely related to the improvement of human technology, modern science and technology, and the overall industry level, especially with the development of mechanical engineering science and mining disciplines.

The general trend of scientific development of mechanical engineering will be digitization, intelligence, precision, miniaturization, life, and ecology. As a branch of the mechanical engineering discipline, mining machinery also follows the general trend of this development. At the same time, combined with the characteristics of the mining industry, its development trend is intelligent, automated and ecological.

Market competition drives mining machinery to intelligent product design is the soul of manufacturing, product structure, function, quality, cost, delivery time and manufacturability, maintainability, post-disposal and human, machine and environmental relations, etc. In principle, it is determined at the product design stage. The innovative design capability of products has become the primary factor that determines the position of enterprises in the global competition.

Mining machinery is a highly technical and highly integrated equipment. The development of new equipment continuously integrates human achievements in various fields, followed by the improvement of materials science, manufacturing technology, information technology, and computer technology. Each round of products has new products. The injection of technology, the shorter and shorter update cycle of parts and components, and the faster the replacement of new equipment, especially the development of large-scale mining machinery, no mature experience can be discerned, and does not allow any mistakes in the design, so it is necessary With the integration of multi-disciplinary technologies, the efficiency of design and quality of design are improved, and the ability for independent innovation and market competitiveness is promoted. Based on the integration of mining machinery and computer technology and network technology, a digital development trend has been formed.

A variety of strategic metal mineral resources are stored on the sea floor to achieve efficient and safe exploitation of marine mineral resources, provide technical support for the protection of the nation’s maritime rights and interests and the development of the national economy, and provide guarantees for sustainable social development. To realize subsea mining, it is necessary to develop intelligent mining machinery equipment such as deep-water cable controlled unmanned submersibles and unmanned, cable-free home-made deep submersibles.

The economic construction needs the automation of mining machinery to follow the development of society and the development of the national economy. The human needs for resources and energy are increasing, and China is a country with relatively poor resources. With the development of resources, the depth of mining has gradually increased, extending from the land to the sea. The prerequisites for resource extraction have been deteriorating. The situation of safe mining has become increasingly severe. China's coal mining depth has reached 1000m, the concentration of metal ore has reached 1380m, and the depth of mining has increased. Groundwater, gas, high ground stress, and geological structure have greatly increased the difficulty of extracting resources.

Automatic unmanned face mining is the development direction of underground or hazardous environment mining, and it is also an effective way to ensure the safe mining of working face. Comprehensive use of mining science, automation technology, communications technology, computer science and technology, etc., to carry out the basic theory of automated unmanned face mining research and development of new technologies and new equipment, so that mining machinery will be in the direction of robotization and intelligent development.

Energy-saving and emission-reduction requirements promote the ecologicalization of mining machinery. The “Circular of the State Council on Printing and Distributing the Comprehensive Work Plan for Energy Conservation and Emission Reduction during the Twelfth Five-Year Plan” emphasized that with the acceleration of industrialization and urbanization and the continuous upgrading of the consumption structure, China’s energy demand has grown rigidly. Due to the constraints of domestic resource support capacity and environmental capacity, and global energy security and climate change, the constraints on resources and the environment are increasingly strengthened. The energy saving and emission reduction situation during the “12th Five-Year Plan” period is still very severe and the task is arduous.

For the harmonious development of the natural environment, it is required that the mining machinery be “ecologicalized”, and that various manufacturing techniques, manufacturing resources, and manufacturing processes and manufacturing organizations should be constantly developed to improve the quality of the products, so that the products will not generate environmental pollution or environmental pollution throughout their entire life cycle. Minimize pollution, maximize resource utilization, minimize energy consumption, and ultimately achieve harmonization of corporate economic and social benefits. Efficient and zero-pollution mining machinery has a very good prospect of development.
