五沟煤矿防砂煤岩柱高度留设研究

通过计算机数值模拟、相似材料模拟实验及"三下开采规程"等方法研究五沟煤矿1033工作面需要留设的安全防砂煤岩柱高度,并参考实测成果资料,综合确定出1033工作面留设的防砂煤岩柱安全高度及其开采上限标高,通过资源回收、经济评价表明1033工作面提高开采上限的可行性和必要性.为今后的10煤层含水层工作面留设防砂煤岩柱开采提供大量实际技术经验,回收大量煤炭资源,获得更大经济效益,实现矿井安全开采和可持续发展.

Research on Set Safety Pillar Prevent Sand in WuGou Coal Mine

Through computer numerical simulation, analog material simulation experiment, and regulation for setting eoal pillar and mining under building, water bodies, railways and main roadways etc to research set safety pillar prevent sand in the area 1033 mining face of WuGou coal mine. Refer to the results measured, comprehensive determine the set safety pillar prevent sand and necessity of mining upper limit. Through the resources recycling and the economic evaluation indicate that it is feasibility and the necessity of enhancement mining upper limit. It will provide the massive actual technical background for set safety pillar prevent sand of 10 coal water-bearing stratum mining face in the next and recycle massive coal resources, obtain greater economic efficiency,realize safe mining of the mine and the sustainable development.
