一、前言.桃山煤矿128108面-294m 风巷,因原该面以上工作面采用斜巷出煤,该斜巷在128108面煤体内开掘,因而施工128108面风巷时,就必然存在平巷纵穿斜巷的难题(如图1所示)。二、两种纵深斜巷方案对比,针对这一问题,当时施工队与技术部门存在着两种截然不同的观点。一种观点认为采取穿木鞋,超前用轨道,“U”型卡加固,并制定防止不满顶措施。另一观点则坚持从-340m,8—煤机巷向上逐棚修复斜巷。直到修复完好后,再在斜巷内装木垛,加固棚梁并用木大板护帮,防止施工时风巷底部冒空。
First, the preface .128108 face of the Taoshan Mine -294m air Lane, due to the original face above the work surface using inclined roadway coal, the inclined road in the 128,108 face coal excavation, so the construction of 128,108 face air Lane, there must be vertical lane Oblique lane of the problem (as shown in Figure 1). Second, comparison of two kinds of deep inclined roadway plan In response to this problem, there were two completely different opinions of the construction team and technical department at that time. A view that take to wear wooden shoes, ahead of the track, “U ” card reinforcement, and to develop measures to prevent dissatisfaction. Another point of view is to insist from -340m, 8-coal machine lane up the shed to repair slope. Until the repair is complete, and then install a wooden stack within the inclined lane, reinforcement shed beam and wood panels help to prevent the construction of air at the bottom of the air.
