Coal Mine Integrated Dispatching Communication Solution

Background of the Proposal:

The coal mine dispatching communication system is an essential component of coal mine safety production. An advanced production dispatching command system ensures the rapid and accurate transmission of information through diverse means, guaranteeing the safety of coal mine production.

Solution:

The mining intrinsic safety programmable dispatching machines and touch screen dispatching consoles offer a rich set of integrated dispatching features. They support unified administrative dispatching, enabling one-touch dispatching, direct dialing, group calling, group answering, party-line calling, force insertion, force disconnect, monitoring, and recording. Additionally, they can achieve interconnectivity and collaborative operation with systems such as gas alarm, video surveillance, and personnel positioning, enhancing production management efficiency.

Coal Mining Group Application

Principle of Program Design

　　1. Meeting the safety and production needs of onshore and offshore operations

Coal production primarily takes place underground, where working conditions are harsh (narrow work areas, poor lighting, humidity, and corrosive environments), with numerous safety risks (mainly threats from water, fire, gas, and roof accidents), and high mobility of personnel and equipment. From the perspective of the operational process, there is also a characteristic of combined continuous production among multiple trades underground, often involving heavy equipment. The transportation, installation, and debugging of equipment require close coordination, with timely and accurate information transmission being crucial. At the same time, the management departments and auxiliary production processes at the coal mine surface possess all the characteristics of surface factory production. Therefore, the coal mine communication network must meet both the safety and production needs underground and the demands of surface production, command, management, and people's daily life.

In the design of the coal mine communication network, adhere to the principles of comprehensive planning, phased implementation, and long-term benefits for the communication network. Fully utilize advanced and complete digital dispatching equipment configurations to create a flexible and reliable network structure, thereby building a modern, intelligent coal communication network that meets both short-term and long-term demands for coal production and dispatching command.

　　2. High-reliability production scheduling communication system in place

Due to factors such as multiple mining sites and distant mines, most mining groups require coal dispatch communication systems to fully utilize integrated network concepts and adopt an integrated network communication platform. In addition to establishing an administrative communication system and setting up a central dispatch command center, it is also necessary to establish production dispatch communication systems for the first and second mines, respectively equipped with digital programmable dispatching machines. These can be centrally scheduled and managed by the dispatch command center, allowing the dispatch staff to establish contact with any phone within any communication system at any time through dispatch consoles, achieving quick and convenient, one-touch connectivity. It is possible to establish contact with higher-level dispatches at any time, form a network with them, and enable inter-dialing among mine phones, meeting the needs of modern and advanced coal mining production dispatching and command.

　　Ensuring reliable operation of equipment.

As the modernization of coal production advances, the demand for communication methods and system functions continues to grow. Ensuring that communication information is delivered promptly, accurately, and rapidly is crucial for coal production and operations. The system's construction involves integrating wireless communication with several dispatching program-controlled switches to form an integrated dispatch communication network structure. It must have independent and comprehensive hardware and software measures for fault detection, capable of automatically isolating and diagnosing faults upon occurrence. It should have technologies such as active and standby redundancy, decentralized control, and software fault tolerance, enabling independent survival and clear segmentation in aspects such as structure, functions, business, and equipment management, to effectively ensure reliable equipment operation.

Composition of the Mine-Integrated Scheduling System

　　1. Dispatch Host: The dispatch host is designed to encompass all call, switching, dispatching, multi-system integration, and networking functionalities. It also allows for various configurations to meet user-specific needs.

　　2. Dispatch Console: The dispatch console is a platform for conducting specific operations. Dispatchers can monitor the usage status of all dispatch users through the console and perform dispatch actions. The dispatch console is configured with buttons corresponding to the dialed numbers, enabling one-touch dialing for the console calls.

　　3. PC Terminal Maintenance: The role of terminal maintenance is to control and maintain the operation of the digital dispatching host, including functions such as data management, maintenance, conference call management, and billing management.

　　4. Full-Channel Recording System: Records all通话lines within the entire system.

5. Dispatching Machine Wiring System: Comprising mining communication cables MHYV, mining cable distribution boxes, explosion-proof telephone connection boxes, etc.

　　6. Main Products (Optional) for Host Matching: Mining Telephone Couplers, Mining Communication Cables, Integrated Protection Devices for Communication Lines, Intrinsically Safe Explosion-Proof Telephones.
