We are sad cried, arrived in the evening, effort was done not have on my daughter body, send all over soft, be troubled by all the time, it is such pasts this day night the following day, I still have my Mom to holding the child in the arms to build a car directly with my wife went to city haemal institute, be in when us second when making detailed inspection to the daughter, the leucocyte that discovers a daughter is as high as 610 thousand, red blood cell has 30 thousand only much, the doctor says, your child is too small, if cure, the likelihood can have life risk at any time, if not cure, your child still can live a few days more, hear this news I am about to break down simply, my tear flowed, passed a little while, we let a doctor help us look for bed, let daughter be in hospital, the doctor says, miss your child this circumstance, you are spent namely 100 thousand 200 thousand 1 million, when your child is being treated, life is potential a few minutes of lives were done not have, your child is held in the arms do not answer Hubei, you spend the money in how, also be person money two sky, the doctor says: Do you have remedial money?

我们都伤心哭了，到了晚上，我女儿身上没了力气，浑身发软，一直闹，这天晚上算是这样过去了第二天，我跟我老婆还有我妈抱着孩子直接搭车去了市血液研究所，当我们在次给女儿做详细检查的时候，发现女儿的白细胞高达61万之多，红细胞只有3万多，医生说，你的孩子太小，如果医治，可能随时都会有生命危险，如果不医治，你的孩子还可以多活几天，听到这个消息我简直快要崩溃了，我的眼泪哗啦的就流了下来，过了一会，我们让医生帮我们找床位，让女儿住院，医生说，想你们孩子这个情况，你就是花10万20万100万，你的孩子在治疗的时候，生命可能几分钟命就没了，你们的孩子就抱不回湖北了，你们花在多的钱，也是人财两空，医生说：你们有治疗的钱吗？

Let us cherish life, heart water to water-saving proud to hand, shut the tap, do not let water, air flow.

On the basis of referring the foreign and domestic literatures and systematically generalizing the former research results, firstly, from the adsorption gas, coal spontaneous combustion and the heat resolves, thesis analyzes the ignitable gas occurrence. Secondly, though the experiment station of coal spontaneous combustion, thesis obtains the critical temperature 60 ℃～ 100 ℃, splits temperature 100℃～ 150 ℃, the fission temperature 150℃～ 180 ℃ and the speed-up temperature 210℃～ 250 ℃ and ignitable gas release rules in the several temperatures sections according to the results. Finally according to fire resource and the catastrophe theory, ignitable gas explosion characteristic and the influence factors have been conducted of the qualitative investigation and the quantitative determination. The gas explosion control technologies are put forward. It has built the certain foundation for the effective prevention gas explosion accident occurrence.

本论文采用理论分析和实验模拟相结合的综合研究方法，首先从煤层吸附瓦斯、煤氧复合过程及煤高温热解三方面对采空区可燃性气体的产生进行分析；其次通过对大型煤自然发火实验测试台的应用，根据实验结果得到临界温度60℃～100℃、干裂温度100℃～150℃、裂变温度150℃～180℃和增速温度210℃～250℃等几个温度段的可燃性气体释放规律；最后根据爆炸引火源，结合瓦斯爆炸流变-突变理论，对可燃性气体爆炸特性及影响因素进行了定性研究和定量测定，提出瓦斯爆炸事故的控制对策，为有效预防瓦斯爆炸事故的发生打下了一定的基础。
