针对端头围岩特征，运用UDEC模拟软件分析了工作面不放顶煤长度、端头支护强度以及巷道采用锚杆支护方式等因素与端头顶板稳定的关系。随着不放顶煤长度的增加，端头支护强度的加强及锚杆支护的运用，增强了端头顶板的稳定性。根据某矿S2202工作面生产地质条件，提出了合理的端头不放顶煤长度及端头巷道支护强度。
針對耑頭圍巖特徵，運用UDEC模擬軟件分析瞭工作麵不放頂煤長度、耑頭支護彊度以及巷道採用錨桿支護方式等因素與耑頭頂闆穩定的關繫。隨著不放頂煤長度的增加，耑頭支護彊度的加彊及錨桿支護的運用，增彊瞭耑頭頂闆的穩定性。根據某礦S2202工作麵生產地質條件，提齣瞭閤理的耑頭不放頂煤長度及耑頭巷道支護彊度。

Characteristics of surrounding rock tip, using simulation software to analyze the study UDEC hold top coal mining face length, end support strength and gateway with bolt support and other factors stable relationship with the head end plate. With the increase of the length of the hold top coal strengthening and the bolting end support the use of strength, and enhance the stability of the end plate of the head. Based on the yield and geological conditions of S2202 working face of a coal mine , reasonable length of rejective top-coal caving and supporting strength on face end is put forward.
