综采工作面过断层及揭露尾巷层位控制技术

Layer Level Control Technology of Fully Mechanized Coal Mining Face Passing Through Fault and of Exposed Tail Gateway

为了确保工作面在过断层、揭露尾巷等常见复杂地质条件时的安全,通过加强工作面过断层及揭露尾巷时的工程质量管理,并采用现场跟踪测量高差对工作面截割层位及时调整,实现了工作面过断层和揭露尾巷的安全。实践表明:工作面在过断层和揭露尾巷时,必须加强工程质量管理,采取针对性的技术措施,才能为工作面安全生产创造条件。

In order to ensure the coal mining face safely passing through the fault,exposed tail gateway and other conventional complicated geological condition,with the engineering quality control enhanced for the coal mining face passing through the fault and exposed tail gateway,the height differences of the site tracing measurement could be applied to timely adjust the cutting layer level of the coal mining face and could realize the safety of the coal mining face passing through the fault and exposed tail gateway.The practices showed that when the coal mining face passing through the fault and the exposed tail gateway,the engineering quality control should be enhanced and the relevant technical measures should be taken to create the conditions for the safety production of the coal mining face.
