非等长综采工作面对接生产技术实践

摘要

对非等长综采工作面对接经验技术进行总结，阐述了工作面对接的工艺流程，提出外切眼第一组液压支架的准确定位是里外切眼的无间隙对接的保证，讨论了工作面对接的影响因素及对策。现场验证效果表明：该对接技术可行、经济合理，有效解决了矿井非等长综采工作面回采的技术难题，大大缩短了对接时间，提高经济效益的同时实现了工作面回采期间的安全生产。%This paper made a technical summary of the interconnection technology of fully mechanized coal mining face with different length, elaborated the accurate positioning of the first group hydraulic support in outer cut is key ensuring smooth interconnection process, make of foreign Cut exo gapless butt discuss the factors affecting the face interconnection and taking countermeasures. Field validation results showed: the interconnection technology is feasible and economically reasonable, which effectively solved the technical problems of mines and other fully mechanized coal mining face with different length, greatly reduced the interconnection time, and improved the economic efifciency while achieving production safety during mining face.
