复杂地质条件下矿井开掘支护技术分析

为了探讨了复杂地质条件下煤矿开掘的支护技术,本文首先分析了地壳运动、地质条件的复杂性、支护设备易受外力影响及岩石结构的不稳定性等矿井下复杂地质因素。接着,提出了在此类条件下煤矿掘进支护技术的应用方法,包括正确区分掘机类型、合理选择挖掘机型号、应用临时支护设备、有效防止地下水渗漏以及建立健全技术制度,希望本次研究成功能够为煤矿开掘提供了实用的支护技术方案。

提升矿井开掘工综合能力的实践与思考

基本素养、岗位技能、操作水平是衡量员工综合素质的重要指标。当前公司大力推进专业化能力建设,在薪酬体系与员工操作技能结合日益紧密的情况下,如何通过培训提升员工综合能力,进一步提高公司劳动效率,是一个迫切需要解决的课题。通过对矿井开掘工基本素养、岗位技能、操作水平＂三合一＂培训模式的探索和思考,总结出了提升岗位操作员工综合能力的＂三合一＂培训新模式,并在实践中取得了明显成效。

浅析荷塘矿区的断裂构造特征

荷塘矿区位于湖南省涟源市境内,经地质勘查工作查明煤矿区内断裂构造发育,并具有其独有特征,在实际工作中,从断裂构造特征的研究着手,判断和解决断层给矿井生产造成的影响,并根据具体情况选择合理方案,以便尽量为生产创造安全的工作条件,对今后的煤田勘查工作和矿井开掘、井巷布局均具有现实意义。

Research and development on cutting scale machine in the coal mine shaft

The deposit scale in the coal mine shaft usually causes serious accidents, such as making rope broken, cage seized or dropped. To solve this kind of problems, the re-search of the cutting scale mechanism was made, and a new type of removal scale equipment was made with using imported hard alloy material. The cutting experiment and actual cutting show that it can adapt to abominable condition in the shaft, such as narrow space, wet and excessive shaft crevice water and so on, and can work safely and reliably, and has high cutting scale efficiency. It can also cut out the deposit scale in the circular section of shaft.
