西沙河煤矿永久避难硐室地面钻孔系统设计

Ground Boreholes System Design for Permanent Refuge Chamber in Xishahe Mine

摘要: 煤矿井下发生灾难时，井下原有供氧、供电、监控等设备处于瘫痪状态，无法向永久避难硐室内避险人员提供基本生存条件，西沙河煤矿通过地面钻孔向井下永久避难硐室提供供氧、供电、监控等系统；通过对地面钻孔系统的设计，提高永久避难硐室的可靠性。

Abstract: When the mine occurs disaster, the original devices of oxygen supply, power supply and monitor are destroyed. That can't supply basic living conditions to hedge staffs in permanent refuge chamber. Xishahe Mine provides oxygen power and monitor by ground boreholes to improve reliability of permanent refuge chamber by designing the system of ground boreholes.
