5、更多的、穩(wěn)定性不同的游離基，這時(shí)放出的熱量雖很少，但煤的活性增強(qiáng)；隨著這一過(guò)程的不斷繼續(xù)，在一定條件下，具有自燃傾向性的煤就可能發(fā)展為煤炭自燃。 1.1 coal spontaneous combustion mechanism of the research in recent years, according to the solid organic oxidation theory, some scholars of the spontaneous combustion of coal in our country, especially the oxidation phenomeno

6、n in the early studies showed that the oxidation and spontaneous combustion of coal is a kind of a chain reaction. The coal in the process of its formation formed many oxygen free radicals, such as hydroxyl (OH), carbonyl and carboxyl (-cooh) group (> C = O), etc.; Under low temperature, coal adsorp

7、tion of oxygen from the air and the free radical reaction, generate more, stability of different free radical, then gives off heat, though a few, but the activity of coal increased; As this process continues, under certain conditions, has the spontaneous combustion tendency of coal may be for the de

8、velopment of coal spontaneous combustion. 　　1.1.1煤炭自燃必須具備的四十條件（四要素） 1.1.1 the coal spontaneous combustion conditions of 40 (4 elements) 　1）煤具有自燃傾向性（即在常溫下有較高的氧化活性）；2）具有自燃傾向性的煤呈破碎狀態(tài)并集中堆積存放：3）有連續(xù)的供氧條件；4）熱量易于積聚?！? 1) coal has the spontaneous combustion tendency (i.e., had a higher oxidation activit

9、y at room temperature); 2) has the self-ignition orientation of coal is broken state and focus stacking storage: 3) continuous oxygen condition; 4) the heat is easy to accumulate. 　1.1.2影響煤炭自燃傾向性的因素　　 1.1.2 factors affecting coal spontaneous combustion tendency 1）煤的變質(zhì)程度（煤化程度）炭化程度越高，氧游離基的含量越少。2

10、）煤的成分。含絲煤越多，自燃傾向越大；含暗煤多的煤，一般不自燃。3）煤中的水分。煤中水分少時(shí)，有利于煤的自燃；水分足夠大時(shí)，則會(huì)抑制煤的自燃；但是，煤中的水分蒸發(fā)后，其自燃危險(xiǎn)性會(huì)增大。4）煤的含硫量。同牌號(hào)的煤中，含硫礦物（如黃鐵礦）越多，越易自燃，因?yàn)槊褐兴狞S鐵礦，在低溫氧化時(shí)放出的熱量促進(jìn)了煤炭自燃。5）煤炭的孔隙率和脆性。煤炭的孔隙率越大，越易于自燃。這是由于孔隙率越大，O2越易滲人煤的內(nèi)部，煤的氧化表面積也越大。變質(zhì)程度相同的煤，脆性越大，越易自燃。因?yàn)槊旱拇嘈源笮∨c該種煤巖是否易于破碎和形成煤粉有關(guān)。6）煤層厚度和傾角。煤層厚度或傾角越大，自燃危險(xiǎn)性越大。這是因?yàn)殚_(kāi)采厚煤層或急

11、傾斜煤層時(shí)，煤炭回收率低，采區(qū)煤柱易遭破壞，采空區(qū)不易封閉嚴(yán)密和漏風(fēng)較大。而且，煤是不良導(dǎo)熱體，煤層越厚，越易積聚熱量。若厚煤層分層開(kāi)采，則發(fā)火概率較大。7）煤層埋藏深度。煤層埋藏深度增加，地壓和煤體的原始溫度增加，煤內(nèi)自然水分少.這將使煤的自燃危險(xiǎn)性增加，在開(kāi)采深度不大時(shí)，容易形成與地表溝通的裂隙，造成采空區(qū)內(nèi)有較大的漏風(fēng)，也容易在采空區(qū)中形成浮煤自燃。8）地質(zhì)構(gòu)造。煤層有地質(zhì)構(gòu)造破壞的地方，煤巖發(fā)生自燃比較頻繁。這是因?yàn)槊嘿|(zhì)松碎增加了煤的氧化活性和供氧通道與氧化表面積。在巖漿侵入?yún)^(qū)，煤層受到干餾，煤的孔隙率增加、強(qiáng)度降低，自燃的危險(xiǎn)性也就增大。 1) the metamorphic gr

12、ade of coal char (coalification degree) degree is higher, the less the content of oxygen free radicals. 2) the composition of coal. Contains silk more coal, the greater the spontaneous combustion tendency; Contain dark more coal, the coal usually is not spontaneous combustion. 3) the moisture in coa

13、l. Periods of moisture in coal, coal spontaneous combustion; When water is large enough, can inhibit the spontaneous combustion of coal; However, the moisture in coal after evaporation, the spontaneous combustion risk increases. 4) the sulfur content of coal. With grades of coal, sulfur minerals (e.

14、g., pyrite), the more the more prone to spontaneous combustion, because coal contained in pyrite, gives off heat when low temperature oxidation promote the coal spontaneous combustion. 5) porosity and brittleness of coal. The greater the porosity of coal, the more prone to spontaneous combustion. Th

15、is is due to the porosity, the greater the O2 is easy inside the permeability of coal, coal oxidation surface area. The bigger the same coal metamorphic grade, brittleness, more prone to spontaneous combustion. Because of the brittleness of coal size and whether this kind of coal and rock is easy to

16、 be broken, and pulverized coal formation. 6) coal seam thickness and the inclination. The greater the spontaneous combustion coal seam thickness or Angle, the greater the risk. Because the mining thick coal seam or steep seam, low coal recovery rate, mining area coal pillars is easy damaged, mined-

17、out area not easily closed tight and air leakage is larger. Moreover, coal is poor conductors, the thicker the seam, the more easy to accumulation of heat. If thick coal seam layering mining, the ignition probability is bigger. 7) the buried depth of coal seam. Coal and coal seam buried depth increa

18、ses, the pressure of the original temperature increases, the less coal in natural water. This will lead to increased risk of coal spontaneous combustion, the mining depth is not big, easy to communicate with the surface cracks formation, resulting in goaf air leakage greatly, also easy to form coal

19、spontaneous combustion in goaf. 8) geological structure. With geological structure destruction of coal seam, coal rock spontaneous more frequently. Because breaking up increased coal of coal oxidation activity and oxygen supply channel and oxidation surface area. In magma intrusion zone, by carboniz

20、ation of coal seam, coal porosity increases, the intensity is reduced, the risk of spontaneous combustion is increased. 　　1.2煤自燃發(fā)火危險(xiǎn)性判定（自燃傾向性和發(fā)火期的判定） 1.2 coal spontaneous combustion danger judgement (spontaneous combustion tendency and combustion time of the decision) 　　1）80年代前，煤自燃發(fā)火危險(xiǎn)性的判定沿用原蘇聯(lián)

21、的著火溫度鑒定煤的自燃發(fā)火傾向；但對(duì)高硫煤，用此法判定差異較大。2）近年來(lái)，采用色譜動(dòng)態(tài)吸氧法測(cè)定吸氧量和吸氧速度來(lái)判定自燃發(fā)火傾向。使用的儀器多為ZRJ一1型色譜自燃性測(cè)定儀。3）在研究中采用了兩種途徑來(lái)確定煤的自燃發(fā)火期。即用煤堆實(shí)驗(yàn)裝置在模擬條件下測(cè)定并解算發(fā)火期和測(cè)定煤的吸氧速度、氧化反應(yīng)速度，按照熱傳導(dǎo)及熱平衡原理推算煤的最短自燃發(fā)火期，然后結(jié)合井下各種影響因素確定煤的發(fā)火期。 1) the 80 s, the coal spontaneous combustion dangerous for determining ignition temperature of the form

22、er Soviet union appraisal of coal spontaneous combustion tendency; But for high sulfur coal, determine differences in this way. 2) in recent years, using the method of dynamic oxygen chromatographic determination of oxygen quantity and speed of oxygen to determine spontaneous combustion tendency. In

23、struments used for chromatographic pyrophorisity ZRJ a type 1 meter. 3) in the study used two ways to determine the coal spontaneous combustion period. Box pile experiment under the condition of simulated measuring and calculating combustion time and measuring the rate of oxygen, coal oxidation reac

24、tion speed, the heat conduction and heat balance according to the principle of calculating the shortest spontaneous combustion period of coal, and then combined with various influencing factors of underground coal combustion time is determined. 　　1.3自燃發(fā)火預(yù)測(cè)預(yù)報(bào) 1.3 spontaneous combustion prediction

25、 　　1.3.1預(yù)測(cè)預(yù)報(bào)指標(biāo)最新研究表明，CO已不是在任何情況下都可作為唯一的和最靈敏可靠的判別煤自燃火災(zāi)的指標(biāo)。使用CO、C2H4及C2H2三個(gè)指標(biāo)將煤自燃發(fā)火分為三個(gè)階段。即礦井風(fēng)流中出現(xiàn)CO質(zhì)量分?jǐn)?shù)降至l0-6級(jí)時(shí)的緩慢氧化階段；出現(xiàn)CO和C2H4質(zhì)量分?jǐn)?shù)降至l0-6級(jí)時(shí)的加速氧化階段；出現(xiàn)CO、C2H4和C2H2質(zhì)量分?jǐn)?shù)降至l0-6級(jí)時(shí)的激烈氧化階段（將出現(xiàn)明火）。應(yīng)用這三個(gè)指標(biāo)，不僅可預(yù)測(cè)火災(zāi)，而且還可判Ⅱ其階段，并可據(jù)此采取不同的防滅火技術(shù)措施。 1.3.1 forecasting index, according to new research CO is not in al

26、l cases can be used as the only and the most sensitive and reliable determination index of coal spontaneous combustion fire. Using CO, C2H4 and C2H2 three indicators of coal spontaneous combustion can be divided into three stages. In CO mass fraction is mine love fell to l0 - slow oxidation stage at

27、 level 6; CO and C2H4 quality score dropped to l0 - at level 6 stage of accelerated oxidation; CO, C2H4 and C2H2 quality scores fall to l0 - violent oxidation stage at level 6 (there will be a fire). Application of these three indicators, which not only can predict fire, but also convicted Ⅱ its sta

28、ge, and can therefore take a different technical measures preventing and extinguishing the fire. 　　1.3.2預(yù)測(cè)預(yù)報(bào)手段　 1.3.2 prediction method 　1）70年代前用井下人工采氣樣、地面儀器分析、結(jié)合溫度檢測(cè)人的感知來(lái)判斷發(fā)火危險(xiǎn)性。2）80年代以后，煤礦普遍采用氣相色譜分析方法，并研究應(yīng)用束管監(jiān)測(cè)系統(tǒng)抽吸井下氣體、地面集中分析、微機(jī)自動(dòng)數(shù)據(jù)處理和預(yù)報(bào)自燃發(fā)火。3）最新研制的井下采區(qū)分站式束管系統(tǒng)，如KHY一3井下束管監(jiān)測(cè)系統(tǒng)。這種系統(tǒng)將井下各測(cè)點(diǎn)的氣樣在井下采

34、圍。4）氧氣探測(cè)法。其原理是，煤層自燃后，隨煤溫升高，氧氣濃度上升，依此判斷火區(qū)位置?！? Mine coal spontaneous combustion fire area detection methods are: 1) magnetic detection. The principle is that, after baking the overlying rock magnetism is enhanced by the spontaneous combustion temperature. 2) resistivity detection method. The principl
