摘要:为保障黄土梁界区浅埋煤层安全过沟开采，开展过沟开采工作面涌水量预测研究。采用野外地质调查查明研究区沟道特征，分析研究区煤炭开采沟道洪水充水模式。基于水力学理论，推导黄土梁界区沟道洪水涌入采煤工作面的流量计算公式，并开展工程检验。结果表明：黄土梁界区沟道洪水经产流-汇流-渗流模式涌入采煤工作面；基于采煤工作面产流-汇流-渗流充水模式，提出过沟开采正常和最大涌水量计算公式。经工程实践检验，提出的计算模型能够较准确预测涌水量，误差仅为3.2%。依据涌水量计算公式，提出相应的防治水措施，研究结果可为类似采矿地质条件过沟开采提供借鉴。

Abstract:In order to ensure the safety of shallow coal seam mining across ditches in loess ridge area， the prediction of water inflow of the working face with mining across ditches in loess ridge area was studied. The characteristics of the ditches in the study area were identified by field geological survey， and the flood filling model of the coal mining across ditches in the study area was analyzed. Based on the hydraulic theory， the formula for calculating the inflow of water into the working face in loess ridge area was deduced， and the formula was engineering tested. The results showed that the process of ditches flood entering the coal mining face in the loess ridge area included runoff generation， confluence and seepage. Based on the runoff-confluence-seepage water filling mode， the formulas of calculating the normal and maximum water inflow with mining across ditches were proposed， which could predict water inflow accurately with an error of only 3.2%. According to the formula， the corresponding water control measures were proposed. It provided a reference for similar geological mining conditions with mining across ditches.
