顿巴斯煤层开采条件是极其多样化的。为了在比较少的资料基础上能够确定所研究现象的基本规律和提出相应的、切实可行的建议。巴黎公社矿山冶金学院根据矿压显现强度制定了顿巴斯缓倾斜煤层开采条件的分类法。 根据作者的的看法,这种分类法可以解决广泛的实际问题:正确地评价采矿地质条件;弄清合理地、首次采用立式液压支架的地质条件与技术工艺条件相配合的问题;对动压现象(老顶和直接顶的下沉)实现可靠的预报;在所采用的采面技术工艺中和在顶板下分层强烈下沉期内,预计
The conditions for the development of the Don Bath coal seam are extremely diverse. In order to be able to determine the basic law of the phenomenon under study and to put forward corresponding and practicable suggestions based on a relatively small amount of information. Paris Commune Mining and Metallurgical Institute developed according to the intensity of mine pressure Dunbar gently inclined coal mining conditions classification. According to the author’s opinion, this classification method can solve a wide range of practical problems: correctly evaluate the geological conditions of mining; find out reasonably that the geological conditions for the first time adopting vertical hydraulic supports match the technological process conditions; Phenomenon (old roof and direct roof sink) to achieve reliable forecasting; in the adopted mining technology and under the roof during the intense delamination period, it is estimated
