The invention provides an underground coal mine double-lifting-platform high-position trepanning drilling machine and a drilling machine rollover prevention method.The drilling machine comprises a drilling machine crawler car body, rollover prevention devices are arranged on the upper portion and the periphery of the drilling machine crawler car body, and working lifting devices are installed on the longitudinal rear sides of the rollover prevention devices; an angle adjusting device is rotatably mounted on the top surface of the working lifting device, and a drilling device is movably arranged on the angle adjusting device; an auxiliary lifting device is mounted on the longitudinal front side of the anti-rollover device; according to the method, in the construction process of the drilling machine, whether the drilling machine has rollover danger or not is judged according to the anti-overturning moment. The device has the characteristics of large horizontal tapping height and drilling angle adjusting range and flexible operation and moving, and can meet the requirements of rapid alternate construction with a heading machine and tapping construction along the coal seam height; the anti-rollover capacity in the drilling construction process can be effectively improved, and reliable technical support is provided for safe construction of coal mine underground drilling.
本发明提供了一种煤矿井下双升降平台高位开孔钻机及钻机防侧翻方法,该钻机包括钻机履带车体,钻机履带车体的上方和四周设置有防侧翻装置,防侧翻装置的纵向后侧上安装有工作升降装置,工作升降装置的顶面上可转动式安装有调角装置,调角装置上可移动式设置有钻进装置;防侧翻装置的纵向前侧上安装有辅助升降装置;该方法在钻机施工过程中,根据抗倾覆力矩大小,判别钻机是否有侧翻危险。本发明具有水平开孔高度和钻孔角度调节范围大、运转搬迁灵活的特点,能够满足与掘进机快速交替施工及顺煤层高开孔施工需求;本发明能够有效提升钻探施工过程中的防侧翻能力,为煤矿井下钻探安全施工提供可靠的技术支撑。
