| 摘 要： | 通过理论分析和现场实例，对房柱式采煤的矿压显现规律及其特点进行了探讨。研究表明，房柱式开采时直接顶呈悬顶式周期性垮落；老顶初次垮落步距较常规开采大，且失稳定然；矿压显现强烈，且受煤柱回收顺序的影响。根据现场实际，实施了以顶板垮落步距分析和顶板动态实测相结合的顶板稳定性监测，取得了较好的效果。

| Abstract: | Based on field observations and theoretical analyses, the characteristic of periodic caving of immediate roof and main roof in a room and pillar system was analyzed. The research shows that the first caving distance of main roof is larger in a room and pillar system than in a longwall system, and main roof also has the feature of periodic caving. Its strata behaviors are violent and affected by pillar robbing sequence. From the actual condition, the method combining the analysis of roof caving distance with the dynamic observation of roof was used in the monitor of roof stability and has obtained better effects in practice. |
