In the freeze pore-forming construction process, the control of the radius of inclination target domain is key point of freeze pore-forming. Taking the freeze pore-forming construction of Yuanzigou Coal Mine of Shaanxi Linbei Coal Industry Development Co., Ltd. as an example, this paper focuses on analyzing the control of radius of inclination target domain in freeze pore-forming construction and the practice application of incline prevention and upright guarantee, incline measurement and technical orientation.%冻结造孔施工过程中,控制井斜靶域半径问题是冻结造孔的关键点。以陕西麟北煤业开发有限责任公司园子沟煤矿冻结造孔施工为例,本文着重分析冻结造孔施工中靶域半径控制及钻孔防斜保直、测斜、定向技术实践应用。
