三软煤层煤巷复合顶板支护技术申阳平（陕西澄合山阳煤矿有限公司 陕西渭南

三软煤层煤巷复合顶板支护技术<br>申阳平<br>（陕西澄合山阳煤矿有限公司 陕西渭南 715300）<br>【摘 要】通常情况下在煤矿开采过程中会遇到软的煤层底板岩层、软的顶板岩层和软的主采煤层，这就是三软煤层。这种煤层的构造比较复杂，受到的应力情况相对来说也比较复杂，因此在进行煤矿开采的过程中要重点关注对这一煤层的支护技术开发。复合顶板支护技术在三软煤层中应用比较广泛，它可以很好地维护三软煤层的稳定性。<br>【关键词】三软煤层；顶板支护；煤巷

Composite roof support technology of coal roadway in three soft coal seam<br>Shen Yang Ping<br>(Shaanxi Chenghe Shanyang Coal Mine Co., Ltd. Shaanxi Weinan 715300)<br>[Abstract] usually, in the process of coal mining, there will be soft coal seam floor rock, soft roof rock and soft main coal seam, which is the three soft coal seams. The structure of this kind of coal seam is relatively complex, and the stress situation is relatively complex, so in the process of coal mining, we should focus on the support technology development of this coal seam. Composite roof support technology is widely used in the three soft coal seam, which can maintain the stability of the three soft coal seam.<br>[Key words] three soft coal seams; roof support; coal roadway<br>
