杨柳矿104采区主采煤层为10煤，煤层上为巨厚整体结构坚硬火成岩覆盖，工程地质条件复杂。且由于煤系地层与火成岩在地质结构、强度、变形性能方面存在明显差异，煤层开采中，火成岩下会产生明显离层，并被地下水、瓦斯充填，形成封闭的离层水体、离层瓦斯。覆岩离层水水害具有瞬时水量大、突水征兆不明显、危害大等特点，逐渐被引起重视。Willow mining104 mining area of the main coal seam of coal seam10, overall structure for thick hard igneous rock cover, complicated engineering geological conditions. And because the coal measure strata and igneous rocks in geological structure, strength, deformation performance, there is a marked difference in igneous rock, coal mining, will produce obvious separation, and groundwater, gas filling, to form a closed separation, gas water separation. Overburden bed separation water disaster with instantaneous water, water inrush symptom is not obvious, the characteristics of great harm, is gradually paid attention to.论文以杨柳矿 10414工作面及 104、106 采区为例，以“坚硬覆岩条件及涌水危险性分析”为研究重点，主要研究：厚硬火成岩地质结构条件，包括火成岩的分布、火成岩与10煤的空间分布情况、岩层物理力学性质；采区10煤顶板含水层、隔水层分布情况，裂隙带发育情况；离层形成机理、分布规律；离层水突涌机理。In the mine 10414working face and 104,106 mining area as an example, to" hard strata condition and water gushing hazard analysis" as the research focus, the main research : hard igneous rock geological structure conditions, including the distribution of igneous rocks, igneous rocks and10 coal distribution, rock physical and mechanical properties; in 10coal roof of aquifer, water isolation layer distribution, fracture development situation; abscission layer formation mechanism, distribution law; separation of water inrush mechanism.通过室内试验，得出10煤顶板至下层火成岩底板岩层的物理力学参数，根据岩层的物理力学参数计算出10煤顶板导水裂隙带高度、离层发育位置。理论分析了离层水突水通道形成机理，并提出离层水害防治措施。Through indoor experiment, obtains10 coal roof to the lower layer of igneous rock bottom rock mechanical parameters, according to the rock physical mechanics parameter calculation of10coal roof height of water flowing fractured zone, bed separation development position. Theoretical analysis of bed separation water inrush channel formation mechanism, and put forward the separation water disaster prevention and control measures.

Willow mining104 mining area of the main coal seam of coal seam10, overall structure for thick hard igneous rock cover, complicated engineering geological conditions. And because the coal measure strata and igneous rocks in geological structure, strength, deformation performance, there is a marked difference in igneous rock, coal mining, will produce obvious separation, and groundwater, gas filling, to form a closed separation, gas water separation. Overburden bed separation water disaster with instantaneous water, water inrush symptom is not obvious, the characteristics of great harm, is gradually paid attention to.
In the mine 10414working face and 104,106 mining area as an example, to" hard strata condition and water gushing hazard analysis" as the research focus, the main research : hard igneous rock geological structure conditions, including the distribution of igneous rocks, igneous rocks and10 coal distribution, rock physical and mechanical properties; in 10coal roof of aquifer, water isolation layer distribution, fracture development situation; abscission layer formation mechanism, distribution law; separation of water inrush mechanism
Willow ore mining CaiMeiCeng Lord for 104 10 coal, coal seam for the thick on the whole structure igneous rock hard cover, engineering geology condition is complex. And because of coal formation in geological structure, with igneous rock strength, deformation performance differences, coal bed mining, will produce clear igneous rock overburden bed separation grouting, and underground water, gas filling, form a closed water, overburden bed separation grouting overburden bed separation grouting gas. Overburden water water disasters has instantaneous water volume, water is not obvious, harm big signs and other characteristics, gradually be caused take seriously.
Papers to the 10414 mining face and willow ore 104, 106 mining area as an example, \"and hard strata conditions and poured water hazard analysis\" as the research focus, the main research: thick hard igneous rock geological structure conditions, including the distribution of igneous rock, igneous and 10 coal space distribution, physical and mechanical properties of rock; 10 coal mining roof aquifer, water-resisting layer distribution, fracture zones development situation; Overburden bed separation grouting mechanism, distribution; Overburden bed separation grouting at water poured mechanism.
Through the indoor test results to the roof 10 coal igneous rock bottom physical and mechanical parameters of rock strata, according to the physical and mechanical parameters of rock calculated 10 coal roof lead water fracture zones height, overburden bed separation grouting development position. The theoretical analysis the overburden bed separation grouting water channel formation mechanism of water, and puts forward the prevention and cure measures were abscission layer.
