神府─东胜矿区一、二期工程中新的人为加速侵蚀

在实地考察的基础上，本文论述了矿区工程建设中松散堆积物的形成及其对侵蚀的影响；矿区新的人为加速侵蚀方式及其危害；最后讨论了新的人为加速侵蚀的防治对策.考察区现有松散堆积物1391.77万m³，主要来源于采矿（露天矿及井矿）、铁路、公路建设及采石.根据松散堆积物堆积的地形部位，河道堆积物占总量的60.8%，是造成河道输沙量剧增和行洪障碍物的主要来源.新的人为加速侵蚀导致生态环境进一步恶化，危及矿区的生存和持续发展.1994年上半年，河道的强力清障取得了汛期行洪安全的显着成效.但随着开矿等工程建设的发展，大量松散堆积物的合理堆放、处理，以及因开矿而已破坏的环境的整治任务仍十分艰巨，应作为煤田开发同步进行的环境建设重大项目.

New Man-made Accelerated Erosion during the First and Second Period Construction of the Shenfu-Dongsheng Coal Mining Area

Based on the field investigation, this paper discussed the formation of loose accumulation materials and their Influence on the erosion in the process of construction of coal mining area, as well as the types of the new man-made accelerated erosion and their harms.somemeasures of preventing and controling the new man-made accelerated erosion were.There were 1. 3917 × 10⁶m³ of loose accmulation materials mainly derived from mining, construction of railway and highway as well as exploiting stone According to the positions of loose accumula non materials in the investigated area, the amoumt of accumulation materials in river takes 60.8% of total amount, of which caused sharply increasing of sediment load and was a main source of lansing barrier of flood passing in river course. The new man-made accelerated erosion further deteriorated eco-environment, threaten existence and sustained developement in coal mine area. On the first half year of 1994, forcibly sweeping away the barrier in river course has made a remarkable effect for flood passing safely in high-water season. But with further developing coal mine area, it is also hard that the harnessing task about rationally stacking and treating the large amount of loose acctlnulation materials as well as harnessing envirion ment which will have to he destroied because of mining in very formidable, which should be a qreat program of environmental constuction in the process of developing coal field.
