液压自移支架是综机采面顶板管理的重要支护设备,实践证明:自移支架的正确选用对提高综机采面各项指标,充分发挥综采设备的效能影响极大。因此,针对具体条件,选用合理的自移支架,一般称为“自移支架选型”;依据自移支架技术特征,选择适于它的采面,一般称为“综机采面选择”。虽然前是“依面选架”,后是“依架选面”,但是,两者都须满足同 Hydraulic self-supporting bracket is an important supporting equipment for the roof management of fully mechanized coal mining face. Practice has proved that the correct selection of self-moving bracket has a great impact on improving various indicators of fully mechanized mining face and fully exerting the effect of fully mechanized mining equipment. Therefore, the specific conditions for the selection of a reasonable self-moving stent, commonly known as “self-moving stent selection”; based on the characteristics of self-moving stent technology, choose suitable for its mining face, commonly referred to as “fully mechanized mining face selection.” Although the former is “by-election” and the latter by “election-by-election”, both must satisfy the same
