有煤层自然发火的矿井,为了预防和扑灭矿井内因火灾曾采用了多种方法和措施,其中黄泥注浆是被广泛应用的与之有效的主要措施。为了使黄泥注浆既经济而又有效的起到防灭火作用,在作采区(或火区)防灭火注浆设计时总是对注浆区所需要注入的浆量进行经验计算,然后再以实际的注浆量加以验证。但对实际注浆量的计量,煤矿长期以来都未采用测量仪器进行测定和计量。大多
There are a number of natural coal seam fire, in order to prevent and extinguish the fire inside the mine have used a variety of methods and measures, including yellow mud grouting is widely used and effective main measures. In order to make the yellow mud grouting both economically and effectively play a role in preventing and extinguishing fire, the amount of slurry to be injected in the grouting zone is always calculated empirically in the design of fire extinguishing grouting for the mining area (or fire area), and then Then the actual amount of grouting to be verified. However, the actual amount of grouting measurement, coal mines have not been used for a long time measurement and measurement. most
