中文拼音 [gěikuàngbǎn]
給礦板
英文
feed plate-
In accordance with the occurrence behavior of roof strata and the fracture characteristics of key stratum in shallow seam longwall mining, studied post - buckling behavior of roof key stratum in the process of mining by using initial post - buckling theory, which derived a critical load and a breaking span of the main roof during the first weighting, determined the final subsidence and the maximum rotation angle for broken key stratum, and presented an application with the example of daliuta 1203 face
摘要根據淺埋煤層頂板巖層的賦存特點和長壁開采時關鍵層的變形破斷特徵，應用初始后屈曲理論探討了開采過程中頂板關鍵層的后屈曲性態，得出了老頂初次來壓時頂板的臨界載荷和破斷步距，確定了頂板破斷后的極限下沉量和回轉角，並以神東礦區大柳塔1203工作面為例給出了工程實例。Because it was trouble to control the heavy apron type feeder ' s rotate speed, the paper put forward a new method to achieve control the hydraulic motor speed efficiency by control electro motor rotate speed in transducer to control the hydraulic liquid flux of varable delivery pump
