综采工作面跨采穿层联络巷施工工艺实践

Practices of Fully-Mechanized Face Mining across through Connection Roadway Construction Process

综采工作面过联络巷向来是影响产量及效益的主要因素,通过穿层联络巷更是威胁煤矿安全生产的一大难题,以往过穿层联络巷通常采用打木垛铺设工字钢,回填矸石等方式充填通过,既危险又复杂,严重影响职工安全与煤炭产量。为克服穿层联络巷本身层位关系复杂、岩层夹矸薄顶板难以维护等特点,本文介绍采用高水充填材料对穿层跨采段进行充填的施工工艺,顺利安全的通过穿层联络巷。

The hilly mechanized mining face crossing connection is always the main factors influencing the yield and benefit, by wearing layer contact lane is an even greater problem threaten the safety production of mine, the cross layer connection usually adopting a woodpile laying I-steel, backfilling gangue filling the way, both dangerous and complex, serious impact on employee safety and the output of coal. In order to overcome the characteristics of wear layer contact Lane itself, stratigraphic relations complex rock gangue thin roof hard to maintain, this paper introduces the construction technology of high water filling materials on the wear layer of cross section of filling, smooth and safe by wearing layer connection.
