Stone machinery into the era of numerical control and international standards

The present era has been numerical control, which has four characteristics, namely intelligent, electronic, global, non-group. Automated unmanned mining is the development direction of underground mining or hazardous environment mining, and it is also an effective way to ensure safe mining of working face. Comprehensive use of mining science, automation technology, communication technology, computer science and technology, the basic theory of automated unmanned mining and the development of new technologies and new equipment, so that stone machinery will be robotized and intelligent direction. At present, many industries have entered the numerical control, of course, the stone machinery industry should also follow the pace of development of The Times, and gradually develop in the direction of intelligence, so as to continue to be in line with international standards and the level of development of society.

The development of stone machinery is closely related to human technological progress, modern science and technology and the overall industrial level, especially closely related to the development of mechanical engineering science and mining disciplines. The frontier of modern science and technology has obvious time-domain, domain and dynamic characteristics. Information science, materials science, life science, nanoscience, management science and manufacturing science are the mainstream sciences that will change the 21st century, and the resulting high and new technologies and their industries will change the world. The cross-integration between different sciences will produce new scientific focus, and the development of economy and social progress will produce new requirements and expectations for stone machinery. The general trend of mechanical engineering science development will be digitalization, intelligence, precision, miniaturization, life and ecology. Stone machinery, as a branch of mechanical engineering, also follows this general trend of development. At the same time, combined with the characteristics of the mining industry, its development trend is digital, intelligent, ecological and pleasant. The stone machinery manufacturing industry should continue to integrate the excellent achievements of human beings in various fields, face the major needs of national economic construction, and take the scientific concept of development as the guidance to achieve sustainable development.

There is still a gap between the overall level of China's stone machinery and the international advanced level. In the journey towards the stone machinery manufacturing power, opportunities and challenges coexist. Product design is the soul of the manufacturing industry, product structure, function, quality, cost, delivery time and manufacturability, maintainability, post-scrap treatment and human, machine and environmental relations, in principle, are decided in the product design stage. The innovative design ability of products has become the primary factor that determines the position of enterprises in the global competition.

Stone machinery is highly technical and integrated equipment, the development of new equipment continues to integrate human achievements in various fields, with the progress of material science, manufacturing process, information technology, computer technology, each round of products have new technology injection, parts update cycle is getting shorter and shorter, new equipment replacement is getting faster and faster, especially the development of large stone machinery. There is no mature experience for reference, and no mistakes are allowed in the design, so it is necessary to use the integration of multidisciplinary technologies to improve the design efficiency and design quality, and enhance the independent innovation ability and market competitiveness of enterprises. The digital development trend has been formed on the basis of the integration of stone machinery and computer technology and network technology.

With the development of social progress and national economy, human beings have an increasing demand for resources and energy, while China is a relatively resource-poor country. With the development of resources, the exploitation depth gradually increases, extending from land to sea, the exploitation conditions of resources are deteriorating day by day, and the situation of safe exploitation is becoming more and more serious. China's coal mining depth has reached 1000m, the concentration of metal ore has reached 1380m, the mining depth of ore deposits has increased, groundwater, gas, high ground stress, and geological structure have greatly increased the difficulty of resource mining.
