Among the rock mass weakening technology, gas fracturing is more likely to form complex fracture networks compared with hydraulic fracturing. In order to study the fracture propagation mechanism of gas fracturing in the field of directional fracturing technology, laboratory physical experiments and numerical simulation studies on directional gas fracturing based on the radial guide groove technology were carried out. A preparation method of radial guide groove was proposed, a special sealing fixture was designed to simulate the principle of packer, and the acoustic emission device was used to monitor the gas fracturing process in real time. The experimental results show that the radial guide groove can obviously change the propagation direction of gas fracturing fractures within a certain scale, and the fracture initiation pressure is reduced by about 30% compared with that without guide groove. Under the dynamic loading method of gas fracturing, a unique fracture network of primary fracture and secondary micro-fracture appears, and the fracture width increases by 2-3 times compared with the quasi-static loading method. On this basis, LS-DYNA was used to simulate the dynamic dynamics of transient gas fracturing with or without guide groove. Indicators such as effective plastic strain and von mises stress of the models with and without radial guide grooves were compared and analyzed, and the simulation results are consistent with the laboratory experimental results. The research results can promote the development of directional fracturing technology and rock mass weakening methods for deep hard rocks, and provide technical support for the engineering application of directional gas fracturing technology.

岩体弱化技术中，气体压裂相较于水力压裂更易形成复杂的裂缝网络，为了研究定向压裂技术领域中的气体压裂裂缝扩展机理，开展了基于径向导向槽工艺的定向气体压裂室内物理试验与数值模拟研究。提出了径向导向槽制备方法，模拟封隔器的原理设计了特制密封夹具，并借助声发射装置对气压致裂过程进行了实时监测。试验结果表明：径向导向槽在一定尺度内能显著改变气体压裂裂缝的扩展方向，且对比无径向导向槽试件降低了约30%的起裂压力；气体压裂动态加载方式下出现特有的主裂缝+次生微裂缝的裂缝网络，且裂缝宽度相对准静态加载方式增加了2~3倍。在此基础上，基于LS-DYNA进行了有无导向槽的瞬态气体压裂动力学数值模拟，对比分析了有无径向导向槽模型的有效塑性应变、范式等效应力等指标，模拟结果与室内试验结果一致。研究结果可推动深部硬岩定向压裂技术与岩体弱化方法的发展，为定向气体压裂技术的工程应用提供技术支撑。
