为非燃料矿物开采提供支持活动
Description
本美国行业包括主要从事为非燃料矿物（如沙子、砾石和粘土）开采以及非地质勘探、场地准备、建筑和运输活动（除燃料）的开采提供支持活动的场所，以及非燃料矿物的开采。本行业还包括对这些矿物的勘探。勘探服务包括传统的勘探方法，如取岩芯样本和在潜在地点进行地质观测。

| 21 | 矿业、采石和石油及天然气开采 2-digit sector | 整个行业 矿业、采石和石油及天然气开采行业包括从事自然矿物固体（如煤和矿石）、液体矿物（如原油）和气体（如天然气）开采的场所。 "开采"一词在广义上包括采石、井场作业、提纯（如破碎、筛分、冲洗和浮选）以及其他通常在矿场或作为采矿活动的一部分进行的准备工作。 矿业、采石和石油及天然气开采行业将两种基本活动分为两类：矿场运营和采矿支持活动。 矿场运营包括运营矿场、采石场或油气井的场所，这些场所是自行或以合同或按服务收费的方式为他人运营。 采矿支持活动包括从事按合同或按服务收费的方式进行的勘探（除地质调查和绘制之外）以及/或其他采矿服务（除矿场准备、建设和运输活动之外）。 矿业、采石和石油及天然气开采行业的场所根据开采或要开采的自然资源进行分组和分类。 行业包括开发和/或运营矿场、开采自然资源、提纯（即准备）开采的矿物或提供采矿支持活动的场所。 提纯是提取的材料被减少到可以分离成矿物和废物的颗粒的过程，前者适用于进一步处理或直接使用。 在提纯过程中，主要采用机械方法，如研磨、冲洗、磁分离和离心分离。 相反，制造活动主要使用化学和电化学过程，如电解和蒸馏。 但是，一些处理，如热处理，发生在提纯和制造（即冶炼/提炼）阶段。 准备活动的范围因矿物和任何给定矿床的纯度而异。 虽然一些矿物，如石油和天然气，几乎不需要准备，而另一些则需要冲洗和筛分，而另一些，如金和银，可以在离开矿场之前转化为锭。 采矿、提纯和制造活动经常发生在同一地点。 为了尽可能地收集这些活动，将它们分开记录。 当无法在采矿和制造之间区分收据时，从事非金属矿物开采，然后将非金属矿物提纯为更完善的制造产品的场所应根据该场所的主要活动进行分类。 能够制造少量成品的小型矿场应归类为第 21 行业，矿业、采石和石油及天然气开采。 从事主要为更完善的制造产品开采的场所应归类为第 31-33 行业，制造。 |
| 213 | Support Activities for Mining 3-digit subsector | Industries in the Support Activities for Mining subsector group establishments primarily providing support services, on a contract or fee basis (except geophysical surveying and mapping, mine site preparation, construction, and transportation activities), required for the mining and quarrying of minerals and for the extraction of oil and gas. Establishments performing exploration for minerals, on a contract or fee basis, are included in this subsector. Exploration services include traditional prospecting methods, such as taking core samples and making geological observations at prospective sites. The activities performed on a contract or fee basis by establishments in the Support Activities for Mining subsector are also often performed in-house by mining operators. These activities include taking core samples, making geological observations at prospective sites, excavating slush pits and cellars, and such oil and gas operations as spudding in, drilling in, redrilling, directional drilling, and well surveying; running, cutting, and pulling casings, tubes, and rods; cementing and shooting wells; perforating well casings; acidizing and chemically treating wells; cleaning out, bailing, and swabbing wells; and operating oil and gas field gathering lines. Establishments primarily engaged in providing site preparation and related construction activities on a contract or fee basis are classified in Sector 23, Construction. Establishments primarily engaged in providing transportation activities in support of mining, quarrying, or oil and gas extraction are classified in Sector 48-49, Transportation and Warehousing, based on the primary activity. |
