| description | Steeply dipping seam is still internationally recognized as a complex and difficult coal seam. There are many and extensive coal seams in China with excellent coal quality. In recent ten years, the advanced longwall fully-mechanized mining technology of steeply dipping seam has developed rapidly, the working environment has been improved, the labor intensity has been reduced, and the safety level has been improved. However, there have been some urgent problems to be solved, such as low output and poor efficiency. The economic advantages and investment benefits of fully-mechanized mining technology cannot be fully exerted, which restricts the efficient and sustainable development of fully-mechanized mining in steeply dipping seam. Based on years of systematic research and engineering practice, the comprehensive analysis shows that the production efficiency of fully-mechanized mining in steeply dipping seam is mainly restricted by six factors, such as geology, equipment, technology, personnel, management and others, and the weight of each factor is determined. According to the weight of each influence factor, we should take targeted measures such as Precise detection, precise maintenance, precise operation, precise management, precise training and precise supplement In particular, we should pay more attention to the development direction of mining automation and intelligence, and take it as the core accurate countermeasure for promoting production and efficiency of fully-mechanized mining in steeply dipping seam, so as to fundamentally change the passive situation of large number of people and low production efficiency of fully-mechanized mining in steeply dipping seam. The goal of safety, high yield and reducing human efficiency in long wall comprehensive mining in steeply dipping seam is realized. |
