1. General Requirements

The system must utilize virtual reality technology and multi-person collaboration technology to enable multiple mine rescue personnel to log in simultaneously and conduct coordinated rescue drills in a simulated disaster environment. During the drills, rescue personnel should operate according to their respective task assignments, interact with the system, and complete all collaborative rescue training tasks, including ground alarm reception, ambulance team dispatch, disaster area reconnaissance, mine map annotation, medical first aid, and disaster handling. The system should be capable of generating collaborative rescue drill reports.

1) Developed using computer-based 3D virtual reality technology;

2) Supports 1 to 10 rescue personnel training online simultaneously;

2. Main Functional Requirements

1) Mine roadway terrain loading module: It should be capable of 3D graphic drawing and editing of roadways and generating 3D roadway terrain. It should be equipped with a model library of common underground equipment and facilities, as well as a character model library for rescue personnel, trapped or deceased individuals, escapees, and injured persons. Character models and underground equipment/facility models can be placed into the 3D roadway terrain to create scenarios for drills.

2) Drill task editing module: It should have the function of setting up drill tasks. It should allow editing of gas levels, injured personnel, disaster locations, roof damage positions, equipment types, and quantities within the roadways.

3) Online Collaborative Drill Module

It should enable online rescue drills for common disasters such as coal mine gas disasters, floods, fires, and roof collapses.
