为了提高光明矿稀缺煤种资源的采出率,使其采区采出率达标,提出采用沿空掘巷留窄煤柱技术、加长综采工作面长度、连续采煤机短壁开采技术综合提高5号煤层的采区资源采出率。研究结果表明,此3种技术在5号煤层的应用,将实现综采工作面参数的合理调整和采区边角煤的回采,并使2个采区资源采出率分别由原来的82.1%和80.3%提升至85.4%和86.9%,均可达到最新国家规范对稀缺煤采区资源采出率的要求,可为后期开采实践提供坚实的理论基础。
為瞭提高光明礦稀缺煤種資源的採齣率,使其採區採齣率達標,提齣採用沿空掘巷留窄煤柱技術、加長綜採工作麵長度、連續採煤機短壁開採技術綜閤提高5號煤層的採區資源採齣率。研究結果錶明,此3種技術在5號煤層的應用,將實現綜採工作麵參數的閤理調整和採區邊角煤的迴採,併使2箇採區資源採齣率分彆由原來的82.1%和80.3%提升至85.4%和86.9%,均可達到最新國傢規範對稀缺煤採區資源採齣率的要求,可為後期開採實踐提供堅實的理論基礎。

In order to improve mining ratio of scarce coal in Guangming Colliery, it was put forward that applying driving roadway along shallow coal-pillar, prolonging mining face and short-wall mining with continuous coal miner. Results showed that application of the 3 technologies in 5th coal-seam would rationally optimize full-mechanized mining face, make boundary coal mined and improve resource mining ratio of 2 mining zones from 82. 1% and 80. 3% to 85. 4% and 86. 9% , which would reach the requirement of state regulation for scarce coal resource and provide theoretical basis for later mining practice.
