Coal demand soars intelligently into a high ground for business

Have you ever thought that the mine will also "think" yourself? Have you heard that equipment will choose different operating methods based on geological conditions? Have you seen the machine itself to recognize the hardness of the rock? These are not just talk about it, but are the functions that China's intelligent coal machines need to achieve.

With the gradual depletion of domestic coal-prone areas, the difficulty of coal mining is also increasing. To ensure the safety of coal energy in China, and to ensure that high-efficiency coal mining areas continue to maintain high efficiency, it must be on the equipment. Efforts to improve the efficiency of the use of mechanized equipment to ensure the strategic safety of China's coal resources. Then, to achieve this goal, we must make efforts in the digitization and intelligentization of coal mining machinery.

The domestic coal-fired machine enterprises are striving to build intelligent coal machines. At the Beijing International Coal Machinery Exhibition recently held, Sany Heavy Equipment put forward the concept of “smart mines” for the first time, becoming a brand-new bright spot for the exhibition and even the entire coal-machinery industry. The beginning of the intelligentization of Chinese coal machinery. The intelligent development of coal products will be a main theme of the development of the coal machinery industry during the “Twelfth Five-Year Plan” period.

The so-called "smart mine" is to make all the equipment used in underground coal mines intelligent, so that the entire production mine will form an intelligent cluster of equipment. After several years of rapid development in the coal machinery industry, the traditional equipment process has basically matured. How to achieve new innovations and breakthroughs on the original basis will be a wise choice for building digital and intelligent mining equipment.

Taking the roadheader as an example, in the past, roadheaders used throughout the world, whether made domestically or imported, could only be engaged in a single type of work. For example, hard rock roadheaders can only excavate rocks of a specified hardness, and soft rock roadheaders must only target soft rocks. Excavation. However, SANY reloading the TBM currently developed has an intelligent processor. The machine itself can recognize the hardness and hardness of rock, and can also determine which strength and method to use for excavation based on geological conditions. This roadheader will be revolutionary, will completely change the production mode of the coal mine, and maximize the production efficiency. The "smart mine" will let the entire production system of the coal mine itself "think".

Intelligentization and automation have always been the development direction of SANY reloading machine products while pursuing high quality.

As early as April 2007, SANY reloaded for the first time put forward the concept of “joint coal mining unit” with the concept of “integration” and “automation”, and immediately started to develop the first comprehensive design and manufacturing based on integrated design in China. The use of complete sets of equipment—smart automatic coal mining units—has triggered the intelligent development of Sany Heavy Equipment.

After more than two years of painstaking research, at the end of 2009, the QMZ300 and 200 combined coal mining units rebuilt by SANY have been put into use in the Qipanjing Mine in Inner Mongolia and the Dongda No.

It is understood that the joint coal mining unit through the central control system to achieve the entire set of fully integrated mining equipment, centralized monitoring and management, build a high degree of automation of coal mining, coal transportation and support system. The central control room is responsible for the entire coordination work. It is also responsible for the data transmission and communication with the wells. It can finally realize the remote control and operation of the fully-mechanized mining equipment, thereby realizing automatic coal mining in the unmanned area. In addition, the coal mining unit also has the function of memory cutting and coal and rock recognition. Multi-sensor fusion technology is used to identify the distribution of working face coal rock, and the automatic adjustment of the shearer traction speed and rocker arm height is achieved. The intelligent analysis is used to realize the downshift, fall rocker arm bypass, speed reduction hard cut, and hard fault shutdown. And other cutting modes.
