Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and computational investigations, aims to establish fundamental understanding of key processes controlling fracture formation in brittle materials (coal seams and porous rocks) under the action of hydraulic fracturing. The research outcomes will help to assess and minimise the risks associated with the hydraulic fracturing technology.

水力压裂技术是一种通过注入高压流体来提高含资源岩石的水力导流能力的技术，很少有技术能像水力压裂技术那样引起人们的广泛关注。人们担心的是使用过的化学品泄漏到上覆含水层、不必要的地震事件和地面沉降等不确定性。本研究将实验研究与计算研究相结合，旨在对脆性材料（煤层和多孔岩石）在水力压裂作用下控制裂缝形成的关键过程建立基本认识。研究结果将有助于评估和最小化与水力压裂技术相关的风险。
