Abstract
The utility model relates to a kind of coal mine down-hole gas safety monitoring system, it is characterized in that: by underground monitoring communication base station, well external monitor main website, fire damp sensor group, well head firedamp sensor, electric power generating composition, fire damp sensor group, well head firedamp sensor is connected with underground monitoring communication base station by RS485 interface, power supply is underground monitoring communication base station, fire damp sensor group, well head firedamp sensor is powered, underground monitoring communication base station connects fiber cable cross connection box by TCP/IP interface with optical cable, this fiber cable cross connection box is connected with well external monitor main website.The utility model scientific structure design is reasonable, by fire damp sensor group and well head firedamp sensor Real-Time Monitoring down-hole and well head gas density, and transfer to well external monitor main website by underground monitoring communication base station, check for Control Room, display screen is set in down-hole simultaneously, be convenient to staff watch in real time, when gas density is too high, employing mine ventilation and control gas such as to be gushed out the method, prevent gas density from exceeding regulation, have structure simple, cost is low, the advantage that practicality is good.
Description
Technical field
The utility model relates to mining equipment monitoring system, particularly a kind of coal mine down-hole gas safety monitoring system.
Background technology
China's coal-mine accident frequently occurs, and the safety problem of underground coal mine is more and more subject to the attention of state security department and colliery unit.Gas explosion is mine disaster main and common.Gas explosion reaches between 5%-16% when gas (CH4) concentration, and gas mixes with air, at high temperature abrupt oxidization, and produces the phenomenon of shock wave, is the major disaster in coal production.Burning things which may cause a fire disaster mainly electric spark and the explosion of China's coal mines gas explosion, main scene is getting working face.The instantaneous temperature that coal mine gas from explosion produces can reach 1850 ~ 2650 DEG C, and pressure can reach 9 times of first pressing, and near quick-fried source, gas outwards impacts with speed more than hundreds of rice per second, makes casualties, and tunnel and equipment facility damage.After blast, oxygen concentration reduces, and generates a large amount of CO2 and CO, has and suffocate and toxic hazard.Especially the coal mining enterprise that a lot of scale is less, does not have perfect monitor and early warning system, causes the frequent generation of mine disaster.Therefore, carrying out quick and precisely these hazards of mine gas content, Real-Time Monitoring and early warning, is the important means solving Frequent Coal Mine Calamities.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one can effective monitoring fire damp concentration, and transfers to downhole communication base station, thus realizes the coal mine down-hole gas safety monitoring system of quick and precisely early warning.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of coal mine down-hole gas safety monitoring system, it is characterized in that: by underground monitoring communication base station, well external monitor main website, fire damp sensor group, well head firedamp sensor, electric power generating composition, fire damp sensor group, well head firedamp sensor are connected with underground monitoring communication base station by RS485 interface, power supply is underground monitoring communication base station, fire damp sensor group, well head firedamp sensor are powered, underground monitoring communication base station connects fiber cable cross connection box by TCP/IP interface with optical cable, and this fiber cable cross connection box is connected with well external monitor main website.
And, also comprise the display screen be connected with monitoring communication base station, for showing gas density in real time.
Advantage of the present utility model and beneficial effect are:
1, the utility model scientific structure design is reasonable, by fire damp sensor group and well head firedamp sensor Real-Time Monitoring down-hole and well head gas density, and transfer to well external monitor main website by underground monitoring communication base station, check for Control Room, display screen is set in down-hole simultaneously, be convenient to staff watch in real time, when gas density is too high, employing mine ventilation and control gas such as to be gushed out the method, prevent gas density from exceeding regulation, have structure simple, cost is low, the advantage that practicality is good.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of coal mine down-hole gas safety monitoring system, it is by underground monitoring communication base station, well external monitor main website, fire damp sensor group, well head firedamp sensor, electric power generating composition, fire damp sensor group, well head firedamp sensor are connected with underground monitoring communication base station by RS485 interface, power supply is underground monitoring communication base station, fire damp sensor group, well head firedamp sensor are powered, underground monitoring communication base station connects fiber cable cross connection box by TCP/IP interface with optical cable, and this fiber cable cross connection box is connected with well external monitor main website.Also comprise the display screen be connected with monitoring communication base station, for showing gas density in real time.
By fire damp sensor group and well head firedamp sensor Real-Time Monitoring down-hole and well head gas density, and transfer to well external monitor main website by underground monitoring communication base station, check for Control Room, display screen is set in down-hole simultaneously, is convenient to staff and watches in real time, when gas density is too high, employing mine ventilation and control gas such as to be gushed out the method, prevent gas density from exceeding regulation, have structure simple, cost is low, the advantage that practicality is good.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
