  • 摘要：In order to reasonably determine the width of mine artificial boundary coal pillar,simulation study was carried out on it by using FLAC numerical simulation technique according to the mining conditions of a single coal seam,the repeated mining conditions of both upper and lower seams and their different mining sequence,the numerical simulation results showed that since the stress distribution of coal mining and the distribution characteristics of the plastic zone were different,the width of the mine boundary coal pillar to be established was also different,which might be up to 40m to 50m or more. The width of the boundary coal pillar required for the repeated mining of coal seams was about 10m larger than that for the mining of a single one.

  • 摘要：针对新景矿7210综采工作面风速高及疏水性煤尘给喷雾降尘所带来的难题,对喷雾中添加湿润剂提高降尘效果的机理进行了理论分析。在实验室对A型、B型及C型湿润剂降低矿井水表面张力及煤尘沉降时间进行了实验研究,优选出降尘效果较好的A型湿润剂。现场应用表明,喷雾中添加0.35%的A型湿润剂后,采煤机司机处平均粉尘浓度由原来的5242 mg/m3降至376.3 mg/m3,降尘效率达到92.8%,取得了较好的降尘效果。%To counter the problem that the hydrophobic coal dust in 7210 fully mechanized face with high air velocity is difficult to be suppressed by water spray in Xinjing Mine, theoretical analysis was carried out on the mechanism of adding wetting agent into water spray to improve dust removal effect. Experimental study was conducted in the laboratory on the reduction of the surface tension of water and the settlement time of dust by respectively adding Type A, B and C wetting agent into water, and Type A wetting agent with better dust removal effect was the optimum one. The site application showed that the water spray added with 35% Type A wetting agent can reduce the dust concentration at the position of the shearer operator from the original 5 242 mg/m3 to 376. 3 mg/m3 , dust removal efficiency reached 92. 8%, and better dust removal effect was thus achieved.
  • 摘要：To counter to some problems in coal mine safety monitoring, an early-warning system for real-time coal mine safety monitoring based on the wireless sensor networks was designed, and the overall structure of the system was given. This system took MC13213 as the center unit of the wireless sensor network and can carry out the real-time collection and monitoring of the concentrations of CO, O2 and CH4 as well as the air temperature and humidity in the mine. The system also took ARM microprocessor S3C44B0X as the central control component, applied Ethernet to transfer the data to the surface back-office system, which can make data analysis and evaluate the underground environment, and when a dangerous situation occured, the system can send alarm information in advance. The experiments showed that the system has simple structure, stable operation and can accurately pre-warn and predict the coal mine safety.%　　针对煤矿生产环境监测问题，设计了一种基于无线传感器网络的实时煤矿安全监测预警系统，给出了系统的总体结构。该系统以MC13213为无线传感器节点核心，对煤矿井下的CO、O2、CH4气体浓度及矿井空气温湿度进行实时采集和监测；以ARM微处理器S3C44B0X为控制核心，利用以太网将数据传输到井上后台系统，后台系统对数据进行分析并对井下环境进行评价，当有危险情况发生时，系统能提前发出报警信息。试验表明，该系统结构简单、运行稳定，可以准确进行煤矿的安全预警预报工作。
  • 摘要：针对深部软岩巷道围岩的非对称变形破坏问题,通过现场调查研究,分析了巷道非对称变形破坏的原因,提出对薄弱部位采用加强支护的非对称耦合控制对策。巷道围岩变形和锚索承载力监测结果表明,使用50~70 d后围岩的变形趋于稳定,顶板下沉量约为20 mm,两帮移近量小于80 mm。与全断面高强支护相比,非对称支护大大节约了支护成本,取得了良好的效果。%To counter the asymmetric deformation damage of surrounding rock in deep soft rock roadway, this paper analyzed the mechanism of asymmetric deformation of the roadway through field investigation and research, and put forward the asymmetric coupling control countermeasures by strengthening support for its weak parts. The monitoring of the surrounding rock deformation and cable anchor. bearing capacity showed that the surrounding rock deformation tended to a stable state after 50 to 70d, its roof convergence was about 20mm and the shift amount of its two sides was less than 80mm. The application of the asymmetric support can greatly save the supporting cost as compared to the full-section high-strength support, good effect was thus achieved.
  • 摘要：The biggest dust sources in Qidong Coal Mine were the fully mechanized coal faces and fully mechanized heading faces. In this mine, a non-toxic and non-corrosive component water molecule modifier - CHENCA additive was respectively added into the water source for seam infusion and the spraying water source of the heading machine for dust suppression except to taking comprehensive dust removat measures such as water spray,individial personnel protection and so on. This additive can neutralize the magnetic charge of the solid particles in liquid and reduce the surface tension of water. The application of this additive in 3245 (upper) fully mechanized coal face and 6134 fully mechanized heading face of an airway in Qidong Mine showed that it can greatly improve the dust-removal efficiency, with the maximum dust-removal efficiency up to 61. 1%.%　　祁东煤矿粉尘最大来源分别为综采工作面和综掘工作面。矿井除采取喷雾、洒水、个体防护等综合防尘措施外，还分别在回采煤层注水水源和综掘机喷雾水源中加入无毒无腐蚀性复配水分子改性剂———尘克添加剂进行防尘。该添加剂能中和液体中固体颗粒磁荷电性，降低水的表面张力，通过在祁东煤矿3245(上)综采工作面和6134风巷综掘工作面的应用表明，其最高降尘效率达61.1%，提高了降尘效率。
