Fast Tunneling Technology for Roadways with Complex Geological Conditions

智能化是实现煤矿减人增效、提高安全生产保障能力的主要途径之一。以15103运输顺槽掘进为工程背景,针对掘进区域内地质构造复杂的问题,提出将智能化掘进工艺应用到巷道掘进中,以期实现复杂地质条件下巷道快速掘进,并对智能化掘进工艺中涉及到的智能掘进机、智能直驱带式输送机、单轨吊、自移式机尾、锚杆钻车等关键设备等进行分析。现场应用后,15103运输顺槽掘进效率得以显著提升,人员使用数量明显减少,取得了较好的应用成果。

Intelligentization is one of the main ways to reduce the number of people and increase the efficiency of coal mines and improve the ability to ensure safe production.Taking 15103 transportation gateway tunneling as the engineering background,in view of the complex geological structure in the tunneling area,it was proposed to apply the intelligent tunneling technology to roadway tunneling,in order to achieve rapid roadway tunneling in complex geological conditions,and analyze the key equipment involved in the intelligent tunneling technology,such as intelligent roadheader,intelligent direct drive belt conveyor,monorail crane,selfpropelled tail,rock bolt drill truck,etc.After field application,the tunneling efficiency of 15103 transportation gateway has been significantly improved,and the number of personnel has been significantly reduced,which has achieved good application results.
