Therefore, the technical principle of coal spontaneous combustion prevention mainly focuses on isolating coal oxygen contact, cooling, inhibiting chemical reaction of coal oxygen and the like, and measures adopted include grouting, nitrogen injection, carbon dioxide injection, acceleration of working face propulsion speed and the like. The technical measures play an important role in preventing coal spontaneous combustion in the coal mine production process, and practice proves that the measures have failure conditions, so that the occurrence frequency of coal mine spontaneous combustion fires is high.

The invention provides a four-defense line technology for preventing and controlling coal spontaneous combustion, which firstly adopts an active technology and secondly adopts a passive technology, compared with the single passive technology for coal spontaneous combustion control, the method has the advantages of active prediction and prevention in the coal spontaneous combustion control time, passive early warning and emergency can be carried out according to the prediction and prevention results in the early stage after the prevention is invalid, the passive technology effectiveness can be greatly improved, the ventilation module and the spraying module respectively comprise a ventilation fan and a spraying head, the ventilation fan is used for realizing ventilation and air change of air in the coal storage space or the coal-left space and reducing the oxygen concentration, and the smoke induction spray header adopted by the spray header can automatically induce spraying and extinguish fire when a system detects a mistake, in order to realize the control and regulation of the natural condition of the coal, the safety protection is completed by regulating the environment in the space.
Specifically, the working principle of the four-defense line technology system for preventing coal spontaneous combustion is as follows: during the use, detect the condition in storing up coal space or the space of losing the coal: the detection module is used for realizing the distribution detection of the residual coal, the real-time camera monitoring in the space, the air detection module is used for detecting the air components in the coal storage space or the residual coal space, namely the concentration of the air components, and the temperature detection module is used for detecting the temperature in the coal storage space or the residual coal space; analyzing and prejudging the data information detected in the step S1: the risk of the coal nature is detected through the data information detected by the detection module, the possible situation is predicted through a greedy algorithm in the detection process, and then when the coal nature risk is high, the ventilation module and the spraying module are used for reducing the temperature and reducing the concentration of oxygen and methane, so that the coal nature is prevented; then under long-time monitoring, judging fire germination, fire occurrence and fire detection: then, monitoring is carried out in sequence for a long time, the conditions of fire germination, fire occurrence and fire formation are judged, and the fire is controlled and adjusted until the safety state is recovered; and realize data information and transmit and remote control: when the detection module detects the data information, the processing module processes and transmits the data information, and the communication module uploads and downloads the data information to complete the remote control and adjustment of the system; the coal spontaneous combustion development process is divided into five stages of spontaneous combustion risk, germination, occurrence, fire formation and ending on the time sequence, and four defense lines respectively correspond to the state conversion periods of the five stages. The prediction means that according to the relevant theory, experimental data and experience of coal spontaneous combustion, the spontaneous combustion fire hazard and accident can be predicted and judged in advance at what place, namely, the spontaneous combustion hazard source is subjected to space-time prediction. The goal of the prediction is to determine the spatiotemporal distribution of the auto-ignition hazard, the hazard level of the hazard, the extent of impact, and the magnitude of the loss. The coal spontaneous combustion position is predicted to be loose coal body through which air leakage flows, and the coexistence time of the two is longer than the spontaneous combustion ignition period. The prevention is carried out on the basis of prediction to prevent the coal spontaneous combustion risk from being changed into spontaneous combustion germination, and is a core link of spontaneous combustion prevention and control disasters. The goal of prevention is to take technical, engineering and management measures against predicted sources of danger and detected high temperature points, to destroy the conditions of spontaneous combustion, to eliminate the sources of danger and high temperature points and to inhibit the development of self-heating. The early warning is that after the preventive measures are invalid, effective equipment is adopted to collect the sign information of spontaneous combustion, and the position and development degree of the spontaneous combustion (self-heating) source of the coal are judged and reported. The purpose of early warning is to collect and report spontaneous combustion information in time, and to treat and eliminate spontaneous combustion accidents in a bud state. The early warning is carried out by determining early warning indexes and critical values and establishing an early warning system. The emergency is the last line of defense for coal spontaneous combustion prevention and control, aims to prevent the expansion of fire accidents and reduce casualties and economic loss, and is implemented by firstly ensuring personal safety and then protecting the priority sequence of property, so that the loss and the influence are minimized.
