高坑矿是一个具有多发火煤层的矿井,设计能力为年产60万吨,实际生产能力达130万吨以上。先后开采6层煤,其中第3层和第5层为自燃发火煤层,特别是第3层厚度为5～14米,属厚煤层,当地老百姓称它为大槽,实际发火期为2～6个月。由于自燃发火严重,于1956年建立了黄泥注浆站,随着生产发展的需要,在学习全国兄弟单位经验的基础上,结合矿井的具体情况作了一些改进,特别是增加了一座圆形泥浆搅拌池,使泥浆质量得到了提高,泥浆浓度可以任意调
High pit mine is a coal mine with multiple firing coal, design capacity of 600,000 tons per year, the actual production capacity of 1.3 million tons and above. There are 6 layers of coal mining, of which the third and fifth layers of spontaneous combustion seam, especially the third layer thickness of 5 to 14 meters, is a thick seam, local people call it a large groove, the actual firing period of 2 to 6 Months. Due to the serious spontaneous combustion, the Huangni Grouting Station was established in 1956. With the development of production needs, based on the experience of brothers in our country, some improvements have been made according to the specific conditions of the mine, especially the addition of a round Mud mixing tank, the mud quality has been improved, the mud concentration can be adjusted
