【摘要】：隨著我國經濟社會的快速發(fā)展,基礎設施建設項目的擴建,對能源礦產資源的需求量呈快速增長的趨勢,尤其是煤炭資源被大量開采,使得我國大量淺層煤炭礦區(qū)的資源面臨枯竭,煤礦開采逐漸向深部方向發(fā)展,并且豎直方向上的分層重復開采現(xiàn)象越來越常見。厚松散層重復開采條件下地表移動變形特征明顯區(qū)別于非厚松散層的礦區(qū),這些特征主要表現(xiàn)在地表移動變形更加劇烈和沉陷盆地范圍的擴展。要對厚松散層重復開采條件下地表沉陷進行準確預測及控制、實現(xiàn)“三下”壓煤的安全回采,必須深入分析厚松散層重復開采條件下的地表沉陷規(guī)律。本文在淮南礦業(yè)集團某礦工作面觀測站實測資料的基礎上,求取了地表移動變形角量參數(shù)和預計參數(shù),并和首采面的相應參數(shù)做了對比分析。在求取概率積分法參數(shù)的基礎上,對工作面進行了地表移動變形的預計。論文詳細分析了厚松散層重復開采條件下地表移動變形規(guī)律,本文的研究成果對類似厚松散層重復開采條件下的地表沉陷預測及控制、保護煤柱的留設、“三下”采煤均具有一定的理論價值和指導意義。
[Abstract]:With the rapid development of China's economy and society and the expansion of infrastructure construction projects, the demand for energy and mineral resources is increasing rapidly, especially the coal resources are exploited in large quantities. As a result of the depletion of a large number of shallow coal mining areas in China, coal mining is gradually developing towards the deep. And the phenomenon of stratified repeated mining in vertical direction is more and more common. The characteristics of surface movement and deformation under the condition of repeated mining of thick loose layer are obviously different from those of non-thick loose layer mining area. These characteristics are mainly manifested in the more severe deformation of the surface movement and the expansion of the subsidence basin area. It is necessary to accurately predict and control the surface subsidence under the condition of repeated mining of thick loose beds, so as to realize the safe recovery of the "three down" coal compaction. It is necessary to deeply analyze the law of surface subsidence under the condition of repeated mining of thick loose beds. Based on the measured data of a mining face observation station in Huainan Mining Group, the parameters of angle and prediction of surface movement and deformation are obtained in this paper. On the basis of obtaining the parameters of probabilistic integration method, the surface movement and deformation of the face are predicted, and the law of surface movement and deformation under the condition of repeated mining of thick loose layer is analyzed in detail. The research results of this paper have certain theoretical value and guiding significance for the prediction and control of surface subsidence under the condition of repeated mining of similar thick loose beds, the protection of coal pillar retention and the "three down" coal mining.
