摘要:
为研究影响综放开采覆岩“两带”高度预测模型，采用理论分析与经验公式方法系统分析影响覆岩“两带”高度的因素，包括覆岩岩性、覆岩组合结构、煤层赋存状态、顶板控制方法、开采厚度、工作面走向长度与倾向长度、工作面推进速度、覆岩破坏残余变形；并将上述因素划分为采矿地质因素、顶板控制方法、采煤工作面三维尺寸设计参数、时间因素4类；基于此建立综放开采“两带”高度预测模型，并通过工程实例对比、现场实测等方法进行合理性验证。结果表明：芦沟矿与盛泰矿2个工作面的“两带”高度预测值均在实测值范围之内，说明得出的回归式预测效果较好，验证综放开采“两带”高度预测模型的合理性。
Abstract:
In order to study the prediction model of overburden “two-zone” height in the fully mechanized caving mining,the factors influencing the overburden “two-zone” height were systematically analyzed by theoretical analysis and empirical formula method,including the overburden lithology,overburden composite structure,coal seam occurrence state,roof control method,mining thickness,strike length and dip length of working face,advancing rate of working face and overburden failure residual deformation.The above factors were divided into four categories: mining geological factors,roof control methods,three-dimensional size design parameters of coal mining face and time factors.On this basis,a prediction model of “two-zone” height in the fully mechanized caving mining was established,and the rationality was verified by engineering example comparison and field measurement.The results showed that the prediction values of “two-zone” height in two working faces of Lugou mine and Shengtai mine were within the range of field measurement values,which reflected that the regression formula has good prediction effect,and verified the rationality of the prediction model of “two-zone” height in the fully mechanized caving mining.
