Example Embodiment
[0037] This embodiment provides a method for preparing the above-mentioned topsoil substitute material based on the stripped material of an open-pit coal mine. The preparation method includes the following steps:
[0038] Carry out the secondary crushing and air drying of the carbonaceous mudstone. After passing through 2mm and 1mm sieves, take the sieved material and set aside;
[0039] Air-dry the fine sand, and after passing through 2mm and 1mm sieves, take the contents of the sieve for use;
[0040] Air-dry the heart soil, and after passing through a 0.5mm sieve, take the sieve and set aside;
[0041] Air-dry the bottom soil, and after passing through 1mm and 0.5mm sieves, take the contents of the sieve and set aside;
[0042] The mudstone is crushed in two stages, after passing through 3mm and 2mm sieves, take the contents of the sieve and set aside;
[0043] Mix the above-mentioned spare carbonaceous mudstone, fine sand, core soil, bottom soil and mudstone in proportion to obtain t...
Example Embodiment
[0048] Example 1
[0049] A topsoil substitute material based on stripped material from open-pit coal mines, by weight, it is composed of the following ingredients: 10 parts of core soil, 10 parts of bottom soil, 20 parts of mudstone, 10 parts of carbonaceous mudstone, 10 parts of fine sand, and 2 parts of organic fertilizer , 0.5 parts of corn stover and 0.5 parts of water retaining agent.
[0050] The specific preparation method of the above-mentioned topsoil substitute material is as follows: the carbonaceous mudstone is subjected to two-stage crushing and air-drying, after passing through 2mm and 1mm sieves, the sieved material is taken for use; the fine sand is air-dried, after passing through 2mm and 1mm sieves, and then taken into the sieve Air-dry the core soil, after passing through a 0.5mm sieve, take the sieve, and set aside; air-dry the bottom soil, after passing through a 1mm and 0.5mm sieve, take the sieve, and use it; After the 3mm and 2mm sieves, take the sieve and...
