【摘要】：我國(guó)煤炭自燃災(zāi)害比較嚴(yán)重，長(zhǎng)期以來(lái)嚴(yán)重威脅著煤礦的安全生產(chǎn)并影響礦井的經(jīng)濟(jì)效益。巷道松散煤體蓄散熱環(huán)境、漏風(fēng)動(dòng)力和強(qiáng)度以及松散煤體內(nèi)氧氣分布的共同作用下，在巷道變形與起伏帶、巷道交叉應(yīng)力集中區(qū)等地點(diǎn)煤柱內(nèi)常常出現(xiàn)高溫，從而引發(fā)煤自燃火災(zāi)。通過(guò)對(duì)早期煤壁內(nèi)高溫點(diǎn)的測(cè)量，實(shí)現(xiàn)巷道松散煤體自燃火災(zāi)的早期預(yù)警，，對(duì)煤自燃早期階段溫度參數(shù)實(shí)施有效地監(jiān)控，從而防治巷道煤體自燃火災(zāi)的發(fā)生。 論文首先系統(tǒng)綜述了巷道煤體自燃火災(zāi)機(jī)理和預(yù)測(cè)預(yù)報(bào)技術(shù)研究現(xiàn)狀。在此基礎(chǔ)上，基于相關(guān)技術(shù)的研究，結(jié)合新一代單片機(jī)以及集成度高的芯片的電子技術(shù)，在電子元器件選型、溫度傳感器類型的選擇、數(shù)字芯片等硬件電路的設(shè)計(jì)方面加以改進(jìn)和完善，同時(shí)擬采用Protel99SE軟件進(jìn)行硬件電路設(shè)計(jì)和PCB板的布線，用Keil uVision2軟件進(jìn)行源程序編程，以及STC-ISP軟件將源程序下載到設(shè)計(jì)完成的硬件電路，并在實(shí)驗(yàn)室對(duì)溫度探測(cè)儀進(jìn)行微調(diào)校正，開(kāi)發(fā)出適應(yīng)于探測(cè)煤體溫度的儀器。最后開(kāi)發(fā)和研制新的煤體溫度探測(cè)儀，以某煤礦為試點(diǎn)進(jìn)行現(xiàn)場(chǎng)應(yīng)用，實(shí)現(xiàn)對(duì)巷道煤體溫度信息的采集，進(jìn)而得到煤體溫度的準(zhǔn)確實(shí)時(shí)數(shù)據(jù)和變化發(fā)展趨勢(shì)，對(duì)煤層煤自燃火災(zāi)的預(yù)測(cè)預(yù)報(bào)工作起到了較好的先導(dǎo)作用，準(zhǔn)確的提供了可靠的防滅火溫度參數(shù)。
[Abstract]:The coal spontaneous combustion in China is serious, and it has long been a serious threat to the safe production of the coal mine and the economic benefit of the mine. Under the common action of the mass storage environment, air leakage power and strength of the loose coal body in the tunnel and the distribution of the oxygen in the loose coal, the high temperature is often present in the coal pillars such as the tunnel deformation and the fluctuation zone, the cross stress concentration area of the tunnel, and so on, thus leading to the spontaneous combustion fire of the coal. Through the measurement of the high temperature point in the early coal wall, the early warning of the spontaneous combustion fire of the loose coal body in the tunnel is realized, and the temperature parameter of the early stage of the spontaneous combustion of the coal is effectively monitored so as to prevent and control the occurrence of the spontaneous combustion fire of the coal body in the tunnel. In this paper, the mechanism of spontaneous combustion fire of the coal body in the tunnel and the research of the prediction and prediction technology are reviewed in the paper. On this basis, based on the research of the related technology, combining with the new generation of single-chip computer and the electronic technology of the chip with high integration level, it is improved and finished in the aspects of electronic component selection, selection of temperature sensor type, digital chip and other hardware circuits It is good to use the Protel99SE software for the hardware circuit design and the wiring of the PCB board, program the source program with the Keil uvision2 software, and the STC-ISP software to download the source program to the designed hardware circuit and fine-tune the temperature detector in the lab An instrument adapted to detect the temperature of a coal body is developed and finally, the new coal body temperature detector is developed and developed, and on-site application is carried out in a coal mine as a pilot, so that the collection of the temperature information of the coal body in the tunnel is realized, and the accurate real-time data and the change development trend of the temperature of the coal body are obtained The prediction and prediction of the spontaneous combustion of coal in the coal seam plays a better leading role in the prediction and prediction of the spontaneous combustion of coal in the coal seam, and the reliable anti-fire-extinguishing temperature parameter is provided.
