Through a lot of finite element simulation study and similar material experiment, it is systematically revealed the influence law of fault to mining under waterbodies, regressed a series of calculation formula of the failure zone height increase percent caused by fault, and proved by field data. Furthermore, a set of new measures is put forward to control fault when mining under waterbodies.

Gas in working faces is mainly produced in the destressing and desorption process of the coal bed,gobs and adjacent strata.The coal beds are too soft to carry out bedding drilling and draw gas effectively.If gob gas suction is adopted in a large area,the project will prove not only extremely difficult,but also fail to draw out gas of high concentration.Therefore,efficient gas suction is technically determined by seeking fracture aisles for gas movement and gas zone of enrichment.In the course of mining and destressing,...

Gas in working faces is mainly produced in the destressing and desorption process of the coal bed,gobs and adjacent strata.The coal beds are too soft to carry out bedding drilling and draw gas effectively.If gob gas suction is adopted in a large area,the project will prove not only extremely difficult,but also fail to draw out gas of high concentration.Therefore,efficient gas suction is technically determined by seeking fracture aisles for gas movement and gas zone of enrichment.In the course of mining and destressing, gas originating from large destressing areas will go through the fracture aisles of the full development areas and gather in annular fracture areas.The similar material experiments in the laboratory,the numerical simulation and the in-situ study are applied in this work in order to find the location of annular fracture areas in overlying formation.The long-drill mehtod for gas suction along the strike of annular fracture areas is adopted.Mining in coal beds with gas of high conentration and low permeability and gas suction can be operatod separately. During mining activities in the working faces,gas released from roof fracture areas will not flow into upper corners,so the technically drilling problem in soft coal beds with low permeability and high concentration gas can be solved.The application of this technology in the working faces of the gassy mines in Huainan shows that gas suction rate is above 60 percent, making it possible to mine safely,efficiently and intensively.

An algorithm based on area search matching was proposed. The algorithm used color information of measure points to find image grids and to measure the displacement in similar material experiment. The method was an un-touching measurement, and didn't to make special initial point. It could automaticlly create searching criteria during the processing. The method was rapid and reliable. It could solve the interference problem in traditional auto grid methods and avoid the mismatching when the measure points go down to the next line of measure points.

本文提出一种基于区域搜索匹配算法,利用测点的颜色信息寻找网格点,进行相似材料位移的非接触测量。该法不需要特制起始点,可在处理过程中自动生成搜索判据,搜索快速,可较好地解决普通自动网格法局限于灰度图像值的阈值分割,易受图像中各种因素干扰,产生误判的问题,同时也解决了当网格点分布较为密集时,有些变形大的测点会落在下一行网格点中,造成搜索误判的问题。实验表明算法准确可靠,实用性强。
