Introduction Challenges Solutions Results

Introduction

Ningxia Coal Industry Co., Ltd. is a large comprehensive state-owned energy enterprise jointly established by CHN Energy Investment Group and the Ningxia Hui Autonomous Region through joint investment and cooperation. In the coal sector, there are currently 14 pairs of production and construction mines. Among them, Baijigou Coal Mine is rich in the "anthracite", the king of coal. The actual production capacity is stably above 1.6 million tons. It is the largest anthracite production mine in Ningxia and even in the northwest region of China.

Challenges

Numerous potential hazards in production process and environment

The production environment of the mine is complex, encompassing multiple stages such as mining, excavation, machinery operation, transportation, ventilation, washing, and selection. Safety hazards caused by the unsafe state of objects such as conveyor belt malfunctions and workers' violations, the unsafe behavior of personnel, and the unsafe factors of the environment occur from time to time, increasing the production risk of the mine and constraining the improvement of production efficiency and safety level of Baijigou Coal Mine.

Ineffective utilization of camera data

Although Baijigou Coal Mine has deployed a large number of cameras underground to monitor the operation behaviors of underground personnel and the underground production status, in most cases, videos are mainly used for data storage and post-event playback. Even if there are dedicated personnel in the dispatch center responsible for viewing the video camera images, it is impossible to achieve real-time, uninterrupted, and error-free viewing, analysis, and feedback for all important areas.

Solutions

Corerain empowers the Baijigou Coal Mine of Ningxia Coal Industry to construct the application of an industrial AI video analytics system, covering the coal mining, tunneling, main transportation system, auxiliary transportation system and other key underground locations. Based on the coal mine's intelligent safety management monitoring platform, it offers over ten types of AI algorithms, including detection of personnel violations,PPE, operation status of equipment such as coal cutters and scraper conveyors, detection of conveyor belt, detection of monkey cars, and smoke and flame recognition. This enables intelligent identification and real-time early warning of abnormal situations in underground and above-ground production and operation scenarios.

Results

Based on the intelligent perception algorithm model for coal mine safety, Corerain's AI video analytics creates an intelligent coal mine brain for Baijigou Coal Mine. It analyzes the video data of 86 cameras in real time and efficiently. When various violations, dangerous behaviors, and abnormal events occur, it identifies and issues alarms immediately, thereby facilitating safe production at Baijigou Coal Mine.

It has achieved comprehensive integration and visual display of real-time information such as major production links including "mining, excavation, machinery operation, transportation, and ventilation", underground environmental safety, operation management, analysis and decision-making. It accurately grasps the production and transportation status, effectively avoids direct and indirect economic losses caused by major safety accidents. At the same time, it reduces the power consumption due to abnormal idling of coal mine conveyor belts, significantly enhancing the comprehensive management efficiency and intelligent level of the mine.
