在煤矿开采中，大采高回采工艺的实施不仅能够有效提升煤矿回采率和开采速度，也能够有效降低煤矿回采成本。该文以东曲煤矿28204工作面为例，对中厚煤层工作面进行了分析，阐述了回采工艺，论述了大采高工作面的特点及支护设计。
在煤礦開採中，大採高迴採工藝的實施不僅能夠有效提升煤礦迴採率和開採速度，也能夠有效降低煤礦迴採成本。該文以東麯煤礦28204工作麵為例，對中厚煤層工作麵進行瞭分析，闡述瞭迴採工藝，論述瞭大採高工作麵的特點及支護設計。

In coal mine, the implementation of large mining height mining technology not only can effectively improve the coal recovery rate and production rate, but also can effectively reduce the cost of coal mining. In this paper, made the Dongqu coal mine 28204 working face as an example, analyzed brielfy the thick coal seam working face, explained the mining process, and ifnally discussed the large mining height working face features and support design.
