Beschreibung
Zusammenfassung:	The invention discloses a stone open excavation construction method based on supercritical fluid impact rock breaking equipment, belongs to the technical field of rock excavation, and aims to accurately regulate and control high-pressure impact energy, improve rock breaking quality and improve operation efficiency according to different construction scenes or rock types by monitoring a detonation gas pressure value in real time through a pressure sensor. The stone open excavation construction method based on the supercritical fluid impact rock breaking equipment comprises the following steps that S1, a site is cleaned, S2, an initial free face is developed, S3, drill holes are distributed, S4, a pressure relief head enters a hole, S5, a pressurizing energy-gathering agent is filled, S6, hole sealing is conducted, specifically, a packer is started to extrude a hole sealing capsule to enable the hole sealing capsule to be completely expanded, and hole sealing is completed; s7, covering a cannon quilt or a sandb
