Abstract: A wellbore controllable chamber-forming granular-flow mining system, including: a process-well system including a main process well and multiple auxiliary process wells that are in fluid communication with each other, a three-dimensional extension targeted primary fracturing device arranged in the auxiliary process wells and configured to crush or fracture the ore along the extension trajectory of the auxiliary process wells so as to form a chamber of controllable geometry, and a through-well crushing device arranged in the main process well, the auxiliary process wells or the chamber and configured to crush the ore. Fluid is present within the chamber and the process-well system, and the fluid supports the surrounding rock while enabling granular-flow transport of the ore. The chamber is in communication with the wellhead of the main process well, allowing the crushed ore in the chamber to be discharged outside the wellhead of the main process well through the granular flow.

Abstract: A method of using a device for conducting a vascular hemodynamic bionic cell experiment is provided, the method comprises: firstly, experiment preparation; and secondly, experiment operation, namely, switching on a peristaltic pump, pumping a circulation liquid from a collection bottle into an independently corresponding shunting chamber of a corresponding shunting bottle through a collection bottle sampling tube of an independent chamber of a collection bottle, after shunting by the shunting chamber of the shunting bottle, the circulation liquid flowing out of a branch shunting tube flows to a corresponding flow chamber on the 1-3 flow chamber platforms placed side by side, and then converging the circulation liquid to a corresponding independent chamber of the collection bottle through respective sampling tubes of the flow chamber platforms.
