Study of Loading and Running Characteristic of Hydraulic Support in Underhand Mining Face

Abstract: According to complex geological conditions of working face E1108 in Xin-ji mine #2, loading and running characteristic of hydraulic support, influence of depression angle on mining pressure behaviors, as well as relation between advancing speed and the support loading were measured and analyzed. The results indicate that depression angle is inversely proportional to support resistance, in other words, larger depression angle area coincides with lower support resistance area. Moreover, support resistance is gen… Show more

“…Wang et al [10][11][12][13] analysed stress, stability and electro-hydraulic control system of hydraulic support pillar, effectively reducing the failure rate of hydraulic support and increasing its stability. Cheng et al [14] analysed influence of pitch angle coal seam and mining advancing speed on hydraulic support resistance, put forward specific measures to reasonably improve tunnelling speed and control mining height, which are beneficial to direct hydraulic stability. Meng et al [15] established a mathematical model for detecting and controlling pose and orientation through electromechanical fluid simulation, and verified model with different poses to obtain a pose controller, which provides guidance for automation and unmanned underground mining.…”

“…Nevertheless, a strong shield does not necessarily address all the issues in the longwall panel with large-cutting-height. Shield crushing still occurs during the retreating of some panels [4,5]. It is also reported that the roof between the front tip of the shield canopy and the coal face falls occasionally [3,5].…”
