Study on Technical Standard System of Fully Mechanized Top Coal Caving Mining with High Cutting Height

Due to shortages of some related technical standards and technical standard systems of the fully mechanized top coal caving mining technology with hig h cutting height in ultra thick seam in China, the statistic analysis and study were conducted on the related technical standards . According to GB/T13016- -2009 Prepara tion Principle and Requirements of Standard System Table, the standard system of fully mechanized top coal caving mining technology with high cutting height was esta blished.A structure and framework mode of the high cutting fully mechanized top coal caving mining technology standard system were set up.The technical standard sys tem table and the detail list table were determined 62 item standards, including the design code of the high cutting fully mechanized top coal caving mining face, produc tion management regulations and others urgently researched and established were provided in order to improve the mining technology and the equipment standardized level to the thick seam.
