刘桥矿二矿段采煤塌陷区治理工程设计

The design of coal mine collapse treatment of Liu Qiao second mine section

根据刘桥矿二矿段采煤塌陷区塌陷现状,进行了农用地工程设计、农田水利工程设计和道路工程设计。采用散点法计算了土方量,经计算,挖方量余18659.3m3,满足土方回填需求。对农田水利工程进行了灌溉工程布置、灌溉渠道设计和排水工程设计,设计结果为灌水率为0.8560.856m3/s/万亩,渠道设计流量为0.091m/s。对道路工程进行了工程布置和工程设计,设计结果为宽4m的田间道1条,宽2m的生产路5条。设计结果为塌陷区治理提供了依据。

According to the Second mine section of Liu Qiao mine coal mining collapse area of collapse situation, farmland irrigation and water conservancy engineering were designed. Using scatter method to calculation the earth volume, the cut volume was more than 18659.3m^3 ,meeting the needs of earthwork backfilling. Farmland water conservancy projects were arranged in irrigation projects , irrigation channels and drainage engineering design,and the design results for irrigation was 0. 8560. 856m^3/s/mu, channel design flow was 0. 091m/s. The project layout and project design of road works were carried out, and the design result were that there was one road of field road with the wide of 4re,and there were 5 roads of production road with the width of 2m. The results supply basis for the treatment of coal mine collapse.
