我矿自一九四一年建矿以来,曾先后采用分层崩落法、低分段崩落法和无底柱分段崩落法。历年来,井下一直处于高温状态,其中尤以解放初至一九六六年期间更为突出。 我矿井,下产生高温的热源是什么?如何针对这些特点采取相应措施,改善井下的作业条件,以保障职工的身体健康,促进生产,这是生产技术工作中的一项重要课题。 井下高温的来源 从现场的实际情况来看,造成向山矿井下高温的主要热源,大体可以分为以下几个
Since the mine was built in 1941, mine has successively adopted the method of stratified caving, sub-caving and sub-cavern sub-caving. Over the years, the underground has been in a state of high temperature, especially during the period from the first liberation to 1966. What are the heat sources that generate high temperature under the mine? How to take corresponding measures to these characteristics to improve the downhole operating conditions so as to protect the health of the workers and promote the production? This is an important issue in the production technology. The source of underground temperature From the scene of the actual situation, resulting in the main source of high temperature to Xiangshan mine can be broadly divided into the following
