为了解决深部大倾角特厚煤层综放工作面回采巷道围岩极不稳定的问题, 针对运输平巷的全断面来压问题,提出运输平巷沿顶板掘进;同时提出了回风平巷布置的五种可能:负煤柱布置、负零煤柱布置、正下方布置、正零煤柱布置和正煤柱布置,进行了相应的分析后,提出回风平巷应破底板平距1m掘进、在正煤柱位置布置. 该布置方案完善了深部大倾角特厚煤层综放开采体系,解决了回采巷道围岩控制的难题.
為瞭解決深部大傾角特厚煤層綜放工作麵迴採巷道圍巖極不穩定的問題, 針對運輸平巷的全斷麵來壓問題,提齣運輸平巷沿頂闆掘進;同時提齣瞭迴風平巷佈置的五種可能:負煤柱佈置、負零煤柱佈置、正下方佈置、正零煤柱佈置和正煤柱佈置,進行瞭相應的分析後,提齣迴風平巷應破底闆平距1m掘進、在正煤柱位置佈置. 該佈置方案完善瞭深部大傾角特厚煤層綜放開採體繫,解決瞭迴採巷道圍巖控製的難題.

In order to solve the problem of extremely unstable situation for the mining drift surrounding rock in the fully mechanized working face of the Deep Steeply Dipping Thick coal seam,Aiming at the problem of whole section to press for the transport drift,putting forward the scheme of arrangement for transport drift along with the top of roof;Meanwhile putting forward the five possible scheme of arrangement for re-turn air drift:The position of Negative coal pillar,The position of Negative Zero coal pillar,the Position of just below coal pillar, The position of positive Zero coal pillar, The position of positive coal pillar,After analysis on the corresponding,putting forward the best scheme of the return air drift layout is the arrangement of Positive Coal pillar and broking floor 1 meters. the scheme of arrangement improved the system of mining in the Deep Steeply Dipping Thick coal seam,solved the problem of extremely unstable situation for the mining drift surrounding rock control.
