【摘要】 随着综放开采强度不断提高,支护效果差、掘锚自动化程度低等成为厚煤层大断面巷道快速掘进的难题。应用理论分析、数值模拟、力学实验、现场试验等手段,系统研究了厚煤层大断面巷道围岩稳定与掘锚一体化理论与技术,主要研究成果为：(1)建立了厚煤层巷道顶板力学模型,确定了厚煤层大断面巷道宽度；(2)研究了巷道宽度、高度、埋深等因素对厚煤层大断面巷道围岩稳定性的影响规律,得到厚煤层大断面巷道围岩变形与破坏特征。(3)开发了快速及时支护、高阻力临时支护、高预应力锚杆支护掘锚一体化厚煤层大断面巷道围岩控制技术。(4)建立了掘进机三维坐标模型和摆动机构数学模型,实现了掘进机的自动定位与自动截剂,并山PLC和组态王实现了掘锚机远程遥控和自动监测。研究成果在山西潞安集团王庄煤矿井下现场成功应用,提高了掘进速度、降低了成本,取得了显著经济效益和社会效益,对提高我国煤矿掘进的自动化水平具有重要的意义。更多还原

【Abstract】 As the increase of fully-mechanized caving mining strength,the poor supporting effect and low automation degree of digging and anchor integration become difficult problem of quick excavation in thick coal seam large section roadway. Theoretical analysis, numerical simulation, mechanics experiment and field test methods were applied in this paper to systematicly study the theory and technique of rock stability of thick coal seam large section roadway and digging and anchor integration automation. The main conclusions are as follows:(1) a mechanical model of the roof of thick coal seam roadway was set up to determine width of thick coal seam large section roadway. (2) The influence laws of roadway width, height, and buried depth on rock stability of thick coal seam large section roadway were researched and rock deformation and damage features of thick coal seam large section roadway were analyzed. (3) The rock control technology of digging and anchor integration of rapid timely support, high resistance temporary support and high pre-tightening bolting support in thick coal seam large section roadway was developed. (4) 3D coordinate model and swing structure mathematical model were established to achieve the caving and bolting machinery automatic positioning and automatic cutting and realize remote control and automatic monitoring to caving and bolting machinery by PLC.Research results were successfully applied in Wangzhuang Mine of Shanxi Luan mining group, improving the tunneling speed, reducing cost and achieving remarkable economic and social benefits, which has important strategic significance for improving the automation level of our country’s mine tunneling.更多还原
