摘要
晋华宫矿南山井12~#层402盘区8208采煤工作面顶板条件复杂,采煤费时费力且极有可能弃采。就煤岩互层复合型顶板区域、坚硬顶板煤层变薄区域、坚硬顶板应力集中区的开采,提出了实施办法和工艺流程,可避免受影响的25万吨煤量弃采。
Aiming at the special geological conditions at 8208 mining face of 402 Panel of Nanshan Mine in Jinhuagong Colliery,the author proposes the implementation measures and technological process of in mining the areas of coal-rock interbedding withcompound roof, thinned hard roof seam, stress-concentration with hard roof, which can avoid the potential abandoned mining ofcoal output of 0.25 million tons
