我矿下垅坑口401中段东部探矿系长巷道独头掘进,在组织快速掘进的过程中,曾一度由于管理不当,粉尘浓度达不到卫生标准。为了正确解决安全防尘与生产的矛盾,既要狠抓快速掘进,又要实现“向1.5毫克进军”的目标,我们便组织了三结合试验组,在江西冶金研究所、江西冶金学院的协助下,对这一课题进行了认真的调查和试验研究。试验组抓住以风水为主的综合防尘措施,把加强通风作为重要的一环,
In the process of rapid excavation, once mine management failed, the dust concentration did not reach the hygiene standard. In order to correctly solve the contradiction between safety dust prevention and production, we must pay close attention to rapid excavation, but also to achieve the goal of “marching to 1.5 mg.” We organized a three-pronged experimental group to assist Jiangxi Institute of Metallurgy and Jiangxi Metallurgical College Under this topic, conducted a serious investigation and experimental study. The experimental group seized the integrated dust prevention measures mainly based on feng shui and regarded strengthening ventilation as an important part.
