在矿山建设中,未封钻孔是矿床充水、矿山淹井和影响安全生产的重要因素之一。在矿床勘探过程中,虽然能够初步查清矿几床充水因素和矿床开采的技术条件,但是对未封钻孔将会造成淹井,影响矿山建设的问题,却未引起重视,对封孔的目的、意义和要求往往不大明确。致使这项工作很难达到设计和生产的要求,造成矿山生产中的隐患。一、未封钻孔对井巷施工的影响据了解,勘探初期的钻孔,大多数都不封,即使封了质量也不高;因此有不少矿山因此发生突然涌水,造成严重的淹井事故。
In mine construction, unsealed boreholes are one of the important factors that affect the safety of production due to flooding, mine flooding and production safety. In the course of prospecting, though it can initially find out several water-filling factors and the technical conditions for ore-mining, the un-sealed boreholes will cause flooding and affect the construction of mines. However, no attention has been paid to sealing holes The purpose, meaning and requirements are often not clear. As a result, it is very difficult to meet the requirements of design and production in this work and cause hidden dangers in the production of mines. First, the impact of unsealed borehole on the construction of the roadway It is understood that the initial exploration of the drilling, most of them are not sealed, even if the quality of the seal is not high; so there are a number of mines so sudden water influx, resulting in serious flooding ACCIDENT.
