摘　　要：为了解决煤矿通风监测点传统选址方法少考虑空间维度因素的问题,该文利用地理信息系统(GIS)中的基于线性约束下的核密度分析和最短时间可达性评价模型,从空间差异对通风监测点布局的影响的角度出发,选取粉尘作为参考因素,以煤矿实际存在的通风监测点作为验证标准,设计出合理的监测点布局的方案。实验结果表明:①在考虑空间差异的情况下,监测点布局方法与实际通风监测点的一致性分别达到了84.6%和88.9%,证明了该方法的可行性。②通过使用风流最短时间可达性评价模型计算了各风流线路的时间可达值,并评估了可达性数据集的集中性和差异性。结果显示,数据集的差异性较小,各通风监测点之间的风流流通性良好。该文提出的基于线性约束核密度的煤矿通风监测点布局方法具有一定的理论和实际意义。In order to address the issue that traditional site selection methods for ventilation monitoring points in coal mines often overlook spatial dimension factors,this paper uses the kernel density analysis based on linear constraints and the shortest time reachability evaluation model in GIS to design a reasonable layout scheme for monitoring points from the perspective of the impact of spatial differences on ventilation monitoring point layout.Dust is used as a reference factor,and the actual ventilation monitoring points in the coal mine are used as a validation standard.The experimental results are as follows:①When considering spatial differences,the consistency between our monitoring point layout method and the actual ventilation monitoring points reached 84.6%and 88.9%respectively,demonstrating the feasibility of the method.②By using the shortest time accessibility evaluation model,the study calculates the time accessibility values for each ventilation airflow route and assesses the concentration and differences in the accessibility dataset.The results show that the dataset exhibits small differences,indicating good airflow circulation among the ventilation monitoring points.The proposed method,based on linearly constrained kernel density,for coal mine ventilation monitoring point layout has both theoretical and practical significance.
