🔬 Study on Sealing Mechanism of Three-Stage Sealing Under Transient High-Pressure Gas Rock Breaking

-
Image
Breaking 🌋 Introduction to High-Pressure Gas Rock Breaking High-pressure gas rock breaking is an advanced non-explosive technique widely applied in mining, tunneling, and deep geological engineering. 🚧⚙️ This method relies on the rapid release of transient high-pressure gas to induce controlled fracturing of rock masses. However, the efficiency and safety of this process strongly depend on the performance of the sealing system, which prevents premature gas leakage and ensures optimal pressure buildup. 🧩 Concept of Three-Stage Sealing Technology The three-stage sealing mechanism is designed to enhance confinement under extreme transient pressure conditions. 🔒 It typically consists of primary mechanical sealing , secondary expansion sealing , and tertiary adaptive sealing , each functioning at different pressure and deformation stages. Together, these layers work synergistically to resist gas escape and maintain stability during rock fracture initiation. 🛠️ Primary Sealing: Initial ...
