Background of the project
Mining refers to the extraction of naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). This category includes underground or above-ground mining, the operation of mines, and generally all ancillary work performed on or near mine sites aimed at processing raw materials, such as grinding, beneficiation, and processing. Also included are the preparations required to make the raw material available for sale.
Various harmful gases escaping from coal seams, rock formations and tunnel surrounding rocks in the tunnel (the main components are methane, carbon dioxide, carbon monoxide, nitrogen, heavy hydrocarbons and their compounds commonly known as biogas, including ethane, propane, butane and other gases ), is a large number of plant deposits buried deep underground, and the gas produced during the metamorphic carbonization of coal under the action of high temperature and high pressure in the formation under anoxic conditions.

Program overview
With the continuous improvement of underground safety in coal mines, the widespread application of gas monitoring systems, and the improvement of harmful gas detection methods, large and medium-sized mines have formed a detection system that combines manual fixed points, timing detection and automatic monitoring. In the manual detection method, in addition to the sampling analysis method, the current use of portable Gas Detectors is extensive or rapid determination method.
1. Manual fixed-point timing detection scheme
Working in the work area, the portable Gas Detector is a necessary instrument for personal protection and safety. It can detect the change of gas concentration in the working environment in real time, and set the secondary alarm value to ensure that the operators can respond quickly.
2. On-site gas monitoring solution
According to the characteristics of gas production in the industry, Baoshian is equipped with self-developed high-performance fixed gas detection and alarm equipment, which can realize 24-hour all-weather monitoring. At the same time, the Baoshian gas monitoring system can be used with other systems such as fans, valves, sound and light, and fire extinguishing systems through technical protocols to realize the use of networking and achieve the goal of integrated and intelligent safety production.
3. Data transmission scheme
YC-G data remote transmission terminal is a new type of terminal equipment for collecting sensor data with high flexibility and high reliability that our company has carefully researched and developed on the basis of summarizing the design and production experience of many years of data collection equipment. .
The device can be widely used in fixed Gas Detectors and gas control cabinets supporting the modbus protocol. Real-time monitoring of on-site gas concentration, real-time collection and transmission of various data. Through the 485 communication line and the detection equipment connection, the concentration value, decimal point, unit, equipment status and other information can be read in real time, and uploaded to the company's data monitoring server center according to the set time interval.
4. Terminal system solution
Baoshian industrial gas online monitoring platform uses new technologies such as the Internet of Things, cloud technology, big data, and mobile Internet as means to realize real-time gas data reporting, remote control, and equipment management, so as to realize the detection of dangerous gas leakage in the monitoring area. Event monitoring and prompting and alarming can effectively prevent the occurrence of dangerous accidents in enterprises, realize gas leakage and management in the production process, and ensure safe production of enterprises.
Managers can check the real-time values of monitoring area parameters at any time through computers, mobile phones, tablets, etc. When the relevant parameters exceed the limit, an alarm message will be issued to remind the manager to take corresponding measures, and control instructions can be sent to the relevant equipment through the computer or smart phone to realize the remote control of the gas parameters in the monitoring area.
System Features
1. Real-time monitoring, real-time data collection, rapid analysis;
2. Visualized and integrated operation and collaborative environment, quick response and timely guidance;
3. Realize safe production and achieve sustainable business growth.
