利用模糊数学原理,通过确定大倾角煤层的隶属函数和隶属度,对大倾角煤层的倾角范围进行了数值化处理,提出了煤层大倾角范围的建议,有助于大倾角概念的统一和大倾角煤层理论的专门研究,有利于我国大倾角煤层开采理论与技术的发展和国内外学术交流。 By using the principle of fuzzy mathematics, by determining the membership function and membership degree of the coal seam with high dip angle, the dip angle range of the high angle coal seam is numerically treated and the suggestion of the large dip angle range of the coal seam is put forward, which contributes to the unification of large dip angle concept and large dip angle The special study of coal seam theory is conducive to the development of the theory and technology of large-dip coal seam mining in China and the academic exchanges at home and abroad.
