为了研究井下防止火灾蔓延技术,在日本九州煤矿技术研究中心的大型试验巷道进行了一系列试验。试验巷道的长度为400米、断面为5.4米~3。 通过上述大型试验研究了用以井下防止火灾蔓延的防火带的结构适当与否及防火效果如何。此外,对防火带设置水喷雾带的防火效果也进行了试验。 试验结果如下:
In order to study the underground technology to prevent the spread of fire, a series of tests were carried out at a large test lane of Japan’s Kyushu Coal Mine Technology Research Center. The length of the test roadway is 400 meters and the cross section is 5.4-3. Through the above-mentioned large-scale test, the structure of the fire-protection tape used to prevent the fire from spreading downhole is researched properly and the fire-proofing effect is studied. In addition, the fire protection effect of the water spray zone is also tested. The test results are as follows:
