The core of underground coal mine fire control lies in the prevention and control of coal spontaneous combustion. It addresses residual coal oxidation, air leakage, oxygen supply, and heat accumulation across various mining scenarios by establishing an integrated technical system featuring advanced prevention, precise sealing, efficient fire extinguishing, and long-term combustion inhibition. This system enables early identification and control of spontaneous combustion hazards, prevents major fire accidents, and ensures safe mine operation. 1. Key Scenarios and Governance Logic of Coal Spontaneous Combustion Underground coal mine fires mostly occur in hidden areas such as goafs, broken coal pillars, high-level caving zones, abandoned roadways, and corner areas due to continuous oxidation and...

This system integrates the early warning and prevention needs for both internal and external cause fires in mines. Through multi-source data fusion, it achieves integrated perception and panoramic situation display. Relying on a big data platform, it conducts cross-validation of multi-source information, accurate risk identification and intelligent deduction, and supports hierarchical and classified early warning. Based on an expert knowledge base, it automatically generates prevention and control strategies, realizing the full-process closed-loop management and control of "early detection, accurate judgment, rapid response, and effective disposal". It builds a proactive and integrated mine fire prevention and control system that integrates perception, analysis, early warning and decision-making, comprehensively improving the mine's fire...

The mine intelligent ventilation system is a comprehensive mine ventilation management platform that integrates modern sensor technology, the Internet of Things (IoT), big data analysis, artificial intelligence (AI), and automatic control technology.Through real-time perception, intelligent decision-making, automatic regulation, and remote monitoring of downhole ventilation environment parameters, it realizes safe, efficient, energy-saving, and economical operation of the mine ventilation system. Its core concept is to transform from the traditional modes of "determining production based on fixed air volume" (arranging production according to fixed air volume) and "manual experience-based regulation" to the modes of "on-demand ventilation" and "intelligent dynamic regulation", enabling the ventilation system to proactively adapt to the complex and changing...

The coal mine dust suppression system consists of four parts: dust suppression for fully mechanized mining faces, dust suppression for driving faces, dust suppression for belt conveyor transfer points, and dust suppression for roadways. It is managed by one main control box (for data upload) and controlled by multiple sub-control boxes. The ground centralized control software displays the working status and relevant data in real time, and remotely sets the working mode and the start/stop of dust suppression equipment according to the mine working environment. Comprehensive Perception And Intelligent Linkage Control Real-time data collection through multiple types of sensors, and intelligent linkage with production equipment to achieve precise dust suppression....

Industrial dust is a core challenge that restricts production safety, degrades environmental quality, and endangers employee health. Its management must adhere to the core principle of "dust control, suppression, and collection". By integrating process characteristics and on-site scenarios, we build a comprehensive, multi-technology collaborative governance system. This article systematically outlines a complete solution for industrial dust control from three dimensions: governance philosophy, core technologies, and scenario-based applications. I. Governance Philosophy: From Source Control to Systematic Elimination Comprehensive industrial dust control follows a progressive logic: "restriction & guidance → on-site suppression → thorough elimination". Its core is to achieve full-chain management of "source reduction, process suppression, and end-point collection" through technological...

In the process of coal storage and transportation, the industry is plagued by prevalent pain points such as prominent spontaneous combustion risks, uncontrolled coal quality, surging environmental protection pressure and accumulated invalid costs, with personalized challenges in different scenarios: (1) Dynamically Circulated Coal: Unfixed coal storage cycles and extended stockpiling due to power grid peak regulation, a high proportion of blended easily spontaneous combustion coal types. Traditional water-based fire extinguishing tends to cause re-ignition, coal quality damage and frequent environmental problems. (2) Long-term Stored Coal: Storage cycles far exceeding the natural ignition period of coal, rapid oxidative heating inside coal piles, great difficulty in disposal after spontaneous combustion, accompanied by...
